1/16 s

A car is traveling at 21.0 m/s. It slows to a stop at a constant rate over 5.00 s. How far does the car travel during those 5.00 seconds before it stops? (HINT: This is a 2 step problem and you must find the acceleration FIRST)

4.20 m

52.5 m

105 m

158 m

In each of the following cases, determine which car has the greatest acceleration.

speed up from 20m/s to 40m/s in 3 seconds

slow down from 50m/s to stop in 2 seconds

starts from 0 m/s to 20m/s in 5 seconds

Which of the following are considered to be scalar quantities? Pick all that apply.

the acceleration of a runner

the speed of a snail

A feather is dropped on the moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67 m/s². If we wanted to determine the time for the feather to fall to the surface of the moon, which equation should you use to solve the above problem the most efficiently?

A car increases its speed from 9.6 meters per second to 11.2 meters per second in 4.0 seconds. The average acceleration of the car during this 4.0-second interval is
