Question

If a car start from rest and achieve velocity 18kmph in 2s . Then Find its Acceleration.​

Answer 1

Answer:

Nine metre per sec. square

Explanation:

here,

initial velocity u =0m/s

final velocity v= 18 kmph

time t = 2s

now,

18kmph = 5/18*18m/s

=5m/s

Acceleration a = v-u /t

a= 18-0/2s

=> a = 9 m/s^2
