What is the impulse on a car (750 kg) that accelerates from rest to 5.0 m/s in 10 seconds

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.

impulse J = m * (v2-v1) = 750 * (5 - 0) = 3750 (N*s)
