**Equations of Motion – Practice**

**Questions:**

1) A toy car accelerates from rest for 3 seconds at 0.4 m/s^{2}. What is the toys final velocity?

2) If a police car initially travelling at 5 m/s pursues a speeding motorist by accelerating at 1.5 m/s^{2} for 8 seconds before catching up to them, how far does the police car travel in this time?

3) If an eagle achieves a final velocity of 25 m/s by accelerating at 3.5 m/s^{2} for 5 seconds, what was its initial velocity?

4) A car approaching a set of traffic lights is travelling at 14 m/s. The driver sees that the lights have turned red. It takes 4 seconds for the car to come to a complete stop.

a) What was the acceleration of the car over this time?

b) What distance did the car travel during this time?

**Quick**** Answers:**

1) 1.2 m/s

2) 88 m

3) 7.5 m/s

4a) 3.5 m/s^{2} in the opposite direction to which it was travelling (-3.5 m/s^{2}) b) 28 m
