Question

A body starting from rest moving with uniform acceleration has a displamement of 16 m in first 4 seconds and 9 m
in first 3 seconds. The acceleration of the body is
(B) 2 mg-2
(A) 1 mg-2
(C) 3 mg-2
(D) 4 ms-2​

Answer 1

Answer:

Acceleration = final velocity - initial velocity /time

Final velocity =16/4=4m/s

Initial velocity =9/3=3m/s

So acceleration =4-3=1m/s^2
