**How far does a bicycle travel at a speed of 15 m/s for 15 seconds?**

3
**How far does a bicycle travel at a speed of 15 m/s for 15 seconds?**

D = S x T D = 15m/s / 15s D = 1m

4
**A swimmer swims 20 m in 40 s. What is the swimmer’s average speed?**

5
**A swimmer swims 20 m in 40 s. What is the swimmer’s average speed?**

S = D/T S = 20m/40s S = 0.5m/s

6
What is the average speed (mph) for a car journey of 120 miles that began at and finished at noon?

7
What is the average speed (mph) for a car journey of 120 miles that began at and finished at noon? S = D/T D = 120 T = 2.5 hours (from 9:30 – 12:00) S = 120m / 2.5h S = 48 mph

**A person is traveling at 20 m/s in a car when the car hits a tree**

A person is traveling at 20 m/s in a car when the car hits a tree. The person comes to a complete stop in 0.4 seconds. What was the person’s acceleration?

**A person is traveling at 20 m/s in a car when the car hits a tree**

A person is traveling at 20 m/s in a car when the car hits a tree. The person comes to a complete stop in 0.4 seconds. What was the person’s acceleration? a = (0 m/s – 20 m/s)/0.4 s = –50 m/s2

**You throw a ball to a friend. If the ball has a mass of0**

You throw a ball to a friend. If the ball has a mass of0.15kg and it accelerates at 20m/s, what force did you exert on the ball.

11
**You throw a ball to a friend. If the ball has a mass of0**

You throw a ball to a friend. If the ball has a mass of0.15kg and it accelerates at 20m/s, what force did you exert on the ball. F = m x a F = 0.15 x 20 = 3N

12
**You throw a 0. 5 kg ball with a force of 10N**

You throw a 0.5 kg ball with a force of 10N. What is the ball’s acceleration?

13
**M = 0.5 F = 10 N Acceleration = a A = F/m 10 N / 0.5 kg = 20m/s2**

You throw a 0.5 kg ball with a force of 10N. What is the ball’s acceleration? M = 0.5 F = 10 N Acceleration = a A = F/m 10 N / 0.5 kg = 20m/s2
