Question

A body of mass 10 kg is moving with a constant velocity of 10 m/sm/s. When a constant force acts for 4 seconds on it, it moves with a velocity 2 m/secm/sec in the opposite direction. The acceleration produced in it is
​

Answer 1

Answer:

here is your answer mate.

Explanation:

Change in velocity

−2−10=−12

Time required is 4 seconds

a=Δv/t

=−12/4

=−3m/s²
