Question

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

Answer 1

3750Ns

Step-by-step 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.

Answer 2

Step-by-step explanation:

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