ANSWER

Given,

Mass =5 kg

Velocity =4m/s

Net force will be 0 . This is because an object moving with a uniform speed has zero acceleration, there is no change in velocity.

And according to Newton's second law of motion, we know, Acceleration is directly proportional to Force.

If acceleration =0

Force = Mass × Acceleration

Force = Mass × 0

Force = 0

Thus, Net force acting on the body is 0.

Answer 2

0 because velocity is 0 that means acceleration is 0

Force = mass × acceleration

3 × 0 = 0
