Question

An object of mass 2kg is sliding with a constant velocity of 4m/second square on a frictionless horizontal table.The force required to keep the object moving with the same velocity is

A)32N
B)0N
C)2N
D)8N

Answer 1

Answer:

1).Velocity cannot be 4m/s square

Assuming velocity is 4m/s then answer is B)0 cause no friction is acting on the body and no external force is present.
