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.
and this the mass = 30 kg
