Question

An object of mass 200 g starting from rest acquires a velocity of 6 m/s in 4 s.

Answer 1

Explanation:

Since a body starts from rest so

Initial velocity (u)=0 m/s

Final velocity (v)= 10m/s

Time taken to acquire velocity (T)=2 seconds

Acceleration(A)=change in velocity/time taken

V-u/T. =10–0/2 =5m/s^2

Hence accelration is 5m/s^2.
