Question

3) Two people push a car for 3 s with a combined net force of 200 N. (AS1)
(a) Calculate the impulse provided to the car.
(b) If the car has a mass of 1200 kg, what will be its change in velocity?​

Answer 1

Answer:

Given :

Force= 200N

time =3 sec

mass=m=1200kg

Impulse = J= ?

Formula to be used : Impulse = Fx t

=200 x 3 = 600 Ns

B) Impulse J= m ΔV

⇒ ΔV= J/m

⇒600 Ns/1200 kg

=0.5 m/s

Therefor Impulse J is 600Ns

and change in velocity is 0.5m/s.
