Question

A force acting on a body of mass 5 kg ,produces 4 m /sec2 acceleration in it .The value of force will be​

Answer 1

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.
