Question

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: 32 N 0 N 2 N 8 N

Answer 1

Answer:

0 N

Explanation:

F = ma

F = 2*(4-4)/t

F = 2*0/t

F = 0 N

Note: Surface should be frictionless and air resistance is not to be considered

Hope it helps!

Answer 2

Answer:

0 N

Explanation:

Using F=ma formula

F=ma

F=m×a

m=2 ,a=4-4/t

2×0

=0 N
