Question

Rajesh paddles his cycle from stationary position to attain a velocity of 12 m per second in 60 second he apply brake such that the velocity come down to 8 M per second in next 10 second calculate the acceleration in both cases

Answer 1

In 1 st
u=0
v=12
t =60sec
a= v-u/t
a= 12-0/60
a=12/60
a= 1/5 = 0.2 m/s2
