1) An eagle accelerates from 15 m/s to 22 m/s in 4 seconds. What is the eagle's average
acceleration?

2) A roller coaster picks up speed as it rolls down its first hill. Its initial speed is 4 m/s,
and 3 seconds later at the bottom its speed is 22 m/s. What is its average acceleration?

3) A car is said to go "zero to sixty in six point seven seconds (6.7 s)". 60 mph is equal to
26.8 m/s. What is its acceleration in m/s??

4) A car is moving at a speed of 35.8 m/s. What acceleration would it have if it took 2.0 s to
come to a complete stop?
5) A car traveling at 22.4 m/s skids to a stop in 2.55 s. Determine the acceleration of the car.
6) A plane has a takeoff speed of 88.3 m/s. It reached that speed in 30.8 s. Determine the
acceleration of the plane.
7) Rocket-powered sleds are used to test the human response to acceleration. If a rocket-
powered sled is accelerated to a speed of 444 m/s in 1.83 seconds, then what is the
acceleration of the sled?

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
