Question

A ball of mass 4 kg is sliding with a constant velocity of 2 m/s on a frictionless horizontal table. What force is required to keep the ball moving with the same velocity? Option a) 0 N Option b) 2 N Option c) 4 N Option d) 8 N

Answer 1

No force is required to keep the ball moving with the same velocity.

Step-by-step explanation:

To keep the ball moving with the same velocity on a frictionless horizontal table, no force is required. Option a) 0 N is the correct answer. This is because an object in motion will remain in motion at a constant velocity unless acted upon by an external force, according to Newton's First Law of Motion.
