Question

Starting from rest, Aman ride his scooter to attain a velocity of 10 m/s in 40s.

Then he applies brakes such that velocity comes down to 6m/s in s. Calculate

acceleration of scooter in both the cases.​

Answer 1

Answer:

u = 0 m/s

v = 10 m/s

t = 40 sec

a = v-u/t = 10/40 = 0.25 m/s^2

u = 10 m/s

v = 6 m/s

t = 1 sec

a = v-u/t = -4 m/s^2
