Question

starting from a stationary position rahul paadles his bicycle to attain a velocity of 6 m s'in 30 s. Then
he applies brakes such that the velocity
of the bicycle comes down to 4 m s'in
the next 5 s. Calculate the acceleration
of the bicycle in both the cases.

Answer 1

Answer:

CASE-1

ACC.= final velocity-initial velocity/

time

acc.=6-0/30

since answer is 0.2ms^-2

CASE-2

Acc.=0-4/5

since answer is -4/5
