Prerequisite test

These are some questions for studying Work and Energy:

1. State Newton’s second law and calculate the acceleration of a 10 kg mass when a 50 N force is applied to it.
2. A car accelerates from rest at 2 m/s² for 5 seconds. Calculate the final velocity and the distance covered.
3. Which has more kinetic energy: a 2 kg object moving at 3 m/s or a 1 kg object moving at 6 m/s?
