Question

A velocity of mass 2 kg is moving on a smooth floorin a straight line with a uniform velocity of 10m/s .resultant force acting on the body is (in N)

Answer 1

Here v is constant hence a should be zero
Therfore f = ma = m*0=0N

Answer 2

The resultant force acting on the body is 0.

Explanation:

It is given that,

Mass of the body, m = 2 kg

It is moving with a uniform velocity of 10 m/s.

To find

The resultant force acting on the body.

Solution,

The product of mass and acceleration is called force acting on the object. We know that the rate of change of velocity is called acceleration. As the velocity is constant, its acceleration is equal to 0. Hence, the force acting on the body is 0.
