1. Calculating with the “Big Five” a) v = v o + at b) x – x o = v o t + ½at² c) v² = v o ² + 2a(x – x o ) d) x – x o = ½ (v o – v)t e) x – x o = vt - ½at² V = d t a = t v

2. An athlete runs exactly once around a circular track with a total length of 500 m. Find the runner's displacement for the race. Zero Came back to the origin

3. A car drives in a straight line at a constant speed of 5 meters per second for 10 seconds. Find its acceleration. Zero Driving at a constant velocity

4. A remote control car is driven along a straight track at 2 m/s. The child controlling the car then activates the toy's turbo mode so that, 3 seconds later, the car's speed is 3.2 m/s. Find its average acceleration. What variables do you have & need? v = v o + at

6. A car is initially moving at 10 m/s and accelerates at a constant rate of 2 m/s 2 for 4 seconds, in a straight line. How far did the car travel during this time? What variables do you have & need? x – x o = v o t + ½at²

8. A rock is dropped from a cliff that is 80 m above the ground. If the rock hits the ground with a velocity of 40 m/s, what acceleration did it undergo? What variables do you have & need? v² = v o ² + 2a(x – x o )
