Question

An object of mass 5 kg is moving with a constant velocity of 10 ms-1. A constant force acts on
it opposite to the velocity for 4 seconds and gives it a velocity of 2 ms-1 in the opposite
direction. Find the acceleration produced by the force​

Answer 1

Answer:

Change in velocity

−2−10=−12

Time required is 4 seconds

a=Δv/t

=−12/4

=−3m/s²

Hence,
