A 500g cart moving to the right with a speed of 30cm/s collides with a stationary 1500g cart. Immediately after the collision, the 1500g cart is moving to the right at 15cm/s.
a) What is the velocity (magnitude and direction) of the 500g cart just after the collision?
b) Calculate the change in momentum of the 1500g cart (show your calculation).
c) Calculate the change in momentum of the 500g cart (show your calculation).
d) Explain your answers to B and C above in terms of Newton's Third Law and the impulse momentum theorem.
