Answer:

3750Ns

Explanation:

Impulse is defined as Force × time

Force = mass × acceleration,

Hence impulse is;

mass × acceleration × time.

From Newton's second law

Force × time = mass × ∆velocity

750× 5 = 3750Ns

∆velocity = Vfinal-Vinitial ; the initial velocity is zero since the body starts from rest.
