Question

The bicycle is traveling at
4 m/s velocity when the brake is applied it comes ro rest in 2 seconds find the acceleration of the bicycle and comment on the value of acceleration​

Answer 1

Explanation:

a = v-u/t

a = 0-4/2

a = -4/2

a = -2

acceleration is -2m/s²

Answer 2

Answer:

retardation=2 m/s^2

Explanation:

initial velocity=4m/s

final velocity=0m/s

time taken to come at rest=2s

acceleration= final velocity-initial velocity/time

=(0-4/2)m/s^2

= -4/2

acceleration = -2

if acceleration comes in minus then it is retardation.

therefore

retardation=2

or acceleration= -2
