## Do the cars traveled the same direction Why?

The cars will **cover different distances** because they are travelling at different speeds. The distance travelled by the slower car = 50×x miles. The distance travelled by the faster car = 58×x miles.

## At which point do the two cars pass each other?

## How can I find out when two cars will meet?

## Can two cars moving at the same speed have different velocities?

**Objects have the same velocity only** if they are moving at the same speed and in the same direction. Objects moving at different speeds in different directions or both have different velocities. … They represent objects that have different velocities only because they are moving in different directions.

## How long does it take the second car to overtake the first car?

1 Expert Answer

The second car catches up to the **first 4 hours after starting** or 5 hours after the first car departs.

## How many seconds will it take car A to overtake car B?

**7 seconds**.

## Why is it that when cars pass each other at high speeds?

Why is it that when cars pass each other at high speeds on the road they tend to be drawn to each other? **The pressure between them is reduced**. The greater pressure on the far sides of the cars pushes them together.

## What is the average acceleration of the particle over the first 20 seconds?

**10m/s2**.

## During which time interval is the acceleration positive?

**When an object is speeding up the acceleration is in the same direction as the velocity**. Thus this object has a positive acceleration. In Example B the object is moving in the negative direction (i.e. has a negative velocity) and is slowing down.

## Can you find distance without time?

You can ‘consider’ distance without discussing time in a classical sense. We all have **maps and diagrams** which do just that. However to describe the way things actually work and behave time needs to be brought in. This could be looked on as the difference between situations and processes.

## How do you find when two velocities meet?

## How do you find the distance?

**d = st**or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s r = s = d/t.

## When two vehicles moving at the same speed are involved in a collision the vehicle that?

When two vehicles moving at the same rate of speed are involved in a collision the **vehicle that weighs less will take the greater impact** the larger and heavier the vehicle the greater the energy and momentum.

## Can cars go the same speed?

Since **both cars are driving at the same speed** then they should pass the same distance at a given time. Regardless the direction of the cars the lines that represents the distances are equal.

## Can a car that has only been traveling at different speeds?

The is due to the straight line motion of the car. The car is travelling at different velocities and that too east. For the car to travel north at different velocities the car must move in a circular motion. The force and acceleration of the car cannot be in North as the car accelerates towards east.

## How do you calculate overtake time?

## How does a crash at 60 mph compared to a crash at 30 mph?

The faster you go the less time you have to avoid a hazard or collision. The force of a 60 mph crash is not just twice as great as a 30 mph crash **it’s four times as great**!

## How do you calculate safe overtaking distance?

**measured along the center line of the road over which a driver with his eye level 1.2 m above the road surface can see the top of an object**1.2 m above the road surface.

## How many seconds does it take to overtake?

Overtaking is a compromise of safety. It’s safest to follow another vehicle **at least two seconds behind** as this gives you more time to stop and you can see further ahead.

## Why does my car shake behind a semi?

Your car moves and shakes because **as a vehicle moves down the road at high speed it needs to displace the air it is moving into**. As it does this it pushes the air off to the side which will push against vehicles which are passed as it moves down the road.

## Can you determine from the graph when the cars pass each other?

**No**! When lines intersect on a velocity-time graph it means that the two cars have the same velocity. When lines intersect on a position-time graph it means that the two cars are passing each other.

## What is the acceleration of the particle when t 4?

^{2}

**2 m/s**.

^{2}## How do you find acceleration with distance and time?

Calculating acceleration involves **dividing velocity by time** — or in terms of SI units dividing the meter per second [m/s] by the second [s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the meter per second squared .

## Does acceleration have direction?

acceleration rate at which velocity changes with time in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. … Because **acceleration has both a magnitude and a direction** it is a vector quantity.

## Is the direction of acceleration same as the direction of velocity?

Acceleration is a vector in the same direction as the change in velocity **Δv**. Since velocity is a vector it can change either in magnitude or in direction. … Keep in mind that although acceleration is in the direction of the change in velocity it is not always in the direction of motion.

## How do you find the direction of acceleration?

## How do you find the total distance traveled?

The distance travelled is the path taken by a body to get from an initial point to an end point in a given period of time at a certain velocity. If the velocity is constant: **Distance = time * velocity**. d = v*t.

## How do you find time with only distance?

**divide the distance traveled by the rate**. For example if Cole drives his car 45 km per hour and travels a total of 225 km then he traveled for 225/45 = 5 hours.

## What is the formula of distance in motion?

To find distance speed is beside time so distance is **speed multiplied by time**.

## Does distance have direction?

**It has no direction**and thus no negative sign.

## Does distance have direction does displacement have direction?

**displacement are direction aware**. Scalar quantities such as distance are ignorant of direction. In determining the overall distance traveled by the physics teachers the various directions of motion can be ignored.

## How do you find the distance between two speeds and time?

## What is the distance between two coordinates?

**d = √[(x2 x 2 − x1 x 1 )**where (x1 y1 x 1 y 1 ) and (x2 y2 x 2 y 2 ) are the coordinates of the two points.

^{2}+ (y2 y 2 − y1 y 1 )^{2}]## What is the distance between 2 points called?

For any two points there’s exactly one line segment connecting them. The distance between the two points is known to be **the length of the line segment connecting them**. … Segments which have the same length are called congruent segments. We can easily calculate the distance between two points.
