A 2000 kg car is moving at 15 m/sec when it collides with a 1200 kg car sitting still. Briefly compare the impulse imparted on the 1200 kg car by the 2000 kg car to the impulse imparted on the 2000 kg car by the 1200 kg car. Which car undergoes the greater change in momentum? Briefly explain your response.

The 1200 kg car

Explanation:

because it has a lot less weight to keep it still

mass of car 1 = 2000 kg

speed of car 1 = 15 m/s

mass of car 2 = 1200 kg

car 2 is initially at rest.

Impulse (F Δt) = change in momentum = Δ(mv)

Change in Momentum depends on the mass and velocity.

When car 1 collides with car 2, car 1 would under go greater change in the momentum because it has greater mass and initial velocity while car 2 has smaller mass and is initially at rest.   is the answer to the question

d) physical means can be used to separate the components of air.
