1. Speed, Velocity, Acceleration Test #2 How much distance have you run at 18 m/s for 10 seconds? Distance = Speed x Time 18 m/s x 10 s. = 180 m

2. Speed, Velocity, Acceleration Test #13 What is the resultant velocity of a football player who is running 5 m/s forward and is dragged back 3 m/s? Opposite directions – subtract 5 m/s – 3m/s = 2 m/s forward

3. Speed, Velocity, Acceleration Test #15 You are on a bus traveling 8 m/s East. You walk to the back of the bus at a speed of 2 m/s. What is your resultant velocity? Opposite directions – subtract 8 m/s East – 2 m/s West = 6 m/s East

4. Speed, Velocity, Acceleration Test #16 A race car driver goes from 100 mph to 80 mph in 4 seconds. What is the acceleration? 80 – 100 mph 4 s. -5 mph/s

5. Speed, Velocity, Acceleration Test #17 450 – 0 m/s 510 – 0 m/s180 – 0 m/s 3.2 s. 4.8 s. 2.1 s. Car 1 140.53 m/s/s Car 2 106.25 m/s/s Car 3 85.71 m/s/s

6. Speed, Velocity, Acceleration Test #18 A track team competes in 400 m relay. Each leg is 100 meters long. Use the following data to calculate: Leg #1 is 5.4 seconds, #2 is 4.8 seconds, #3 is 5.3 seconds, #4 is 5.6 seconds. 400 meters___________ 5.4 + 4.8 + 5.3 + 5.6 seconds 18.96 m/s

7. Speed, Velocity, Acceleration Test #22 What is the acceleration from C to D? 40 – 20 m/s 1 s. 20 m/s/s

8. Speed, Velocity, Acceleration Test #23 A car travels at 50 mph for 3.5 hours. How far did it travel? 50 mph x 3.5 hr. = 175 miles

9. Speed, Velocity, Acceleration Test #24 In the last part of the race, the runner’s speed changes from 9 m/s to 6 m/s in 3 seconds. What was the acceleration? 6 – 9 m/s 3 s. -1 m/s/s

10. Speed, Velocity, Acceleration Test #25 A bicyclist is bicycling 25 m/s to the North. He realizes he dropped his race tag. He turns around and moves 15 m/s South. What is his resultant velocity? 25 m/s North – 15 m/s South = 10 m/s North
