Answer :
Explanation :
Since , the body is moving with constant velocity of 20 m/s , the change in velocity is 0 .
Acceleration = 0
Since , the acceleration is 0 , the force will also be 0 .
From Newton's second law of motion :
F = m a
F = 2 × 0
Therefore the net force acting would be 0 .
Also , from Newton's first law of motion , a body will be in its position of rest or uniform motion until and unless an external force is applied to it .
Here , the body is in uniform motion , so no external force is applied to it . Hence , the net force on the body is 0 .
