Question

When the brakes of a bicycle were applied, the bicycle was brought to rest from 4ms-1 in 2 minutes. What is the acceleration of the bicycle?
​

Answer 1

Answer:

distance/displacement

Answer 2

Answer:

0.033 m/s^2 in the direction opposite to direction of motion

Explanation:

a = (v-u)/t

u = 4m/s

v= 0

t = 2 min = 120 sec

a = (0-4)/120

   = -0.033 m/s^2 (approx.)

   = 0.033 m/s^2 in the direction opposite to direction of motion
