Assume g = 10 m/s² or 10 N/kg where applicable

1. A car, moving at 1.0 m/s, accelerates at 2.0 m/s² for 3.0 s. What is its final velocity?

2. A 800 kg car is pushed with a force 300 N. If the force of friction experienced is 100 N, determine the acceleration produced.

3. A car moving at 20 m/s skids 20 m to a stop. Find its acceleration.

4. With what velocity would a stone dropped from a height of 12 m reach the ground?

5. How long would a stone thrown at 2.0 m/s vertically into the air take to reach its highest point?
