2. Please select a Team. 30 • Team 1 • Team 2 • Team 3 • Team 4 • Team 5 0

3. Acceleration is the change in velocity 30 • Multiplied by time. • Divided by time. • Plus time 0

4. What is the acceleration of a runner, if she changes her speed from 12m/s 6m/s in 3s? 30 • -2m/s/s • -2mph • -2m/s • 2m/s/s 0

6. If an elephant is running at 10m/s and then stops in 2s, how would you do the math? 30 • 10-0 ÷ 2 = 5m/s/s • 0-10 ÷ 2 = -5m/s/s 0

7. If an elephant is running at 10m/s and then stops in 2s, how would you graph it? 30 • Graph A • Graph B A SPEED TIME B SPEED 0 TIME

8. How long would it take the elephant to travel 5km, running at an average speed of 2km/hr? 30 • time x distance=10hrs • Distance/speed=2.5hrs • Distance/speed=2.5m/s • Speed = distance/time=.4m/s 0

9. Team Scores

10. Which graph represents on object at a constant speed? 30 • Graph A • Graph B A Distance TIME B Distance 0 TIME

11. Are these graphs of acceleration or speed? 30 • Speed • Acceleration A Distance TIME B Distance 0 TIME

12. Calculate slope from 2-4 seconds 30 • 150-50/4-2 = 50m/s • 4-2/250-50 = .02m/s • 250-50/4-2 = 100m/s Distance 0 TIME

13. Team Scores
