Question

An object of mass 3 kg is sliding with a constant velocity of 5 m/s on a frictionless horizontal table.The force required to keep the object moving with the same velocity is
A. 33 N
B.3 N
C. 0 N
D.9 N​

Answer 1

Answer:

0 N

Explanation:

From newton's Ist law of motion, since there is no external force acting on the object it will remain in its original state of motion. Hence, zero force is required to keep the object moving with constant velocity, correct answer is B.

Answer 2

Answer:

The force requires to keep the object moving with the same velocity is

(c) 0N

Explanation:

Hence there is no friction on the surface.

Since there is no external force acting on the object, Newton's first law of motion states that it will remain in its original condition of motion. i.e. a constant velocity.

To keep the object traveling at a constant velocity, zero force is necessary.

Therefore force requires to keep the object moving with the same velocity is 0N.
