Question

As you ride a bicycle on the sidewalk with a speed of
6.4 m/s, a ball suddenly rolls out in front of you. You hit the brakes and
come to rest in 3.8 m. How much time does it take you to stop?

Answer 1

Answer:

1.2 seconds

Explanation:

distance = ((final speed + initial speed) * time)/2

Here given:

• distance: 3.8 meter

• initial speed: 6.4 m/s

• final speed: 0 m/s

Solving steps:

3.8 = ((0 + 6.4) * time))/2

3.8 = 3.2(time)

time = 3.8/3.2

time = 1.1875 seconds ≈ 1.2 seconds
