1. A car is slowing at a rate of 3.5 m/s^2. If it takes 5 seconds for it to come to a stop, what was its initial velocity?
3. A Ferris wheel has a radius of 12 meters and moves at a constant speed of 10 m/s. If you have a mass of 15kg, what is your normal force at the top, in newtons?
4. A force of 136 N is applied at a 45-degree angle over a distance of 12 meters. What is the work done?
6. An object is dropped from a height of 10 meters. How long does it take to reach the ground?
8. A car drives off a 64-meter-high cliff at 20 m/s, how far, in meters, from the base of the cliff does it land?
10. A cart with a mass of 35 kg accelerates down a hill at an angle of 32 degrees. Assuming friction is negligible, what is the cart's acceleration in m/s^2.
11. An object is thrown in the air at 6 m/s. In meters, what is the maximum height it reaches?
12. If an elevator cable has a tension force on the elevator of 138 N, and the elevator's mass is 12 kg, what is the elevator's acceleration?
13. If a student drops a block from a height of 2 meters, how long, in seconds, does it take to reach the ground?

1. A car drives for 30 seconds, starting at 15 m/s and speeding up to 26 m/s. What is its acceleration?
2. Starting from rest, an object accelerates at 12 m/s^2. What is its velocity after 6 seconds, in m/s?
5. A 10 kg box is pulled at a 36-degree angle by a force of 87 N. Assuming friction is negligible, what is its acceleration?
6. A ball is thrown at a 45-degree angle and lands 36 meters away. What is its initial velocity, in m/s?
7. What must your power output be to push an object with a force of 123 N up a 45-degree hill over a distance of 2 meters in 4 seconds?
9. A 3 kg cart moving at 42 m/s hits a second 3kg cart initially at rest and they stick together. What is their final velocity?
11. A 2 kg object going 15 m/s collides with a 4 kg object going 9 m/s and they bounce off each other. The 2 kg object's final velocity is 10 m/s, what is the 4 kg object's final velocity?
