Question

2. An object of mass 2 kg is sliding with a constant velocity of 4 m/s on a
friction less horizontal table. The force required to keep the object moving
with the same velocity is:
(a) 32 N
(b) ON
(c) 2 N
(d) 8N​

Answer 1

0N because force is produced due to acceleration and we have to keep the body in constant velocity which means acceleration is 0.

F = ma

=2×0

=0

Mark me brainliest if you like my answer.

Answer 2

Answer:

Explanation:

Zero as the object is already in motion and surface is friction less which means there is no force required to move it .
