Question

An object of mass 2kg is sliding with a constant velocity of 4m s'1 on a friction less horizontal table. What is the force required to keep the object moving with the same velocity.

Answer 1

Answer:

0N

Explanation:

this is because there is no resistive force on the body and hence no force is required to maintain the velocity of the body at 4ms^-1.As it is already moving with it.A body does not change its state of motion or of rest unless no ext force is applied

Please mark as brainliest if found helpful :)

Answer 2

Answer:

0 Newton

Explanation:

from Newton's first law we know that every object tends to remain in its state of motion or rest so no force is required to keep the object moving with same velocity
