Question

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

(a) 32 N
(b) 0 N
(c) 2 N
(d) 8 N

Answer 1

(b) 0 N
The object will keep on moving on a frictionless horizontal surface by itself due to Newton’s First law of motion.
