1. Calculate the kinetic energy of a 1200 kg car moving at 25 m/s.

2. A 50 kg Go Kart has a kinetic energy of 3600 J. What is its speed?

3. How much work is required to increase the speed of a 1200 kg car from 5 m/s to 10 m/s?

4. Your 1995 Subaru dies on a busy street. Its mass is 1400 kg. It starts from rest and you push with a force of 250 N. How fast is the car going at the end of 10 m?

5. You are driving your 1200 kg at 25 m/s and slam on the brakes, applying a 500 N force, until you slow down to 5 m/s. How far did you travel?
