A car traveling in a straight line at 14 m/s when the driver puts on the brakes and comes to a top in 35 m. What is the average acceleration of the car while it is braking?

-2.8m/s^2

An object traveling in a straight line at 14 m/s when it begins to undergo an acceleration. The object has a displacement of 25 m in the next 5.0 s. What is the acceleration of the car?

-3.6m/s

What is the displacement of a particle that has a position versus time of x(t) = t3-3t from t= 1.0 s to the particle's final position at t=3.0s?

Starting from rest, on a straight road, a car accelerates at 3.5 m/s2. What is the cars velocity after 6.0s?

21m/s

For a car accelerating from rest, assuming all other variables remain unchanged, if you increased the acceleration from a to 2a you would expect the displacement of the car to change from x to

A sprinter running in a straight line passes through two gates at a constant speed of 7.00 m/s. If the first gate is a displacement of 10.0 meters from the starting line, and sprinter passes the second gate 3.00 seconds after passing the first gate, what is the displacement of the second gate from the starting line?

A car traveling in a straight line at 14 m/s when the driver puts on the brakes and comes to a stop in 35 m. How much time did it take for the car to come to a stop?

5s

Cars A and B start at rest and travel with the same acceleration. Compare the speed of car A to car B, after car A has traveled for twice the time of car B.

A is twice as fast as B

Suppose that an object experiences constant acceleration. Which of the following is true?

In equal times its velocity changes by equal amounts.

Which of the following is the NOT a correct relationship between distance and the magnitude of displacement as an object moves from point A to point B along the curved path shown?

The distance is equal to the magnitude of the displacement
