Answer 2

Answer:

Explanation:

Solution :-

Given :-

Change in velocity, (v - u) = 12 m/s

Force, F = 30 N

Mass, m = 5 kg

To Calculate :-

Time, t = ?

Formula to be used :-

F = m(v -u)/t

Substituting the values, we get

F = m(v - u)/t

t = 5(12)/30

t = 60/30

t = 2.0 seconds.

Hence, the force of 30 N be exerted on a body for 2.0 seconds.
