A large mass M with a semicircular cutout lies on a frictionless horizontal surface as shown. A

mass m is released from rest at the right side of the cutout and free to slide down the

semicircular surface which is also frictionless.

a) Is total momentum conserved in this system? Justify (Comm 2 marks)

b) Is any component of momentum conserved in this system? Justify (Comm 2 marks)

c) Use your answer to parts a) and b) to find the speeds of m and M once m reaches the

bottom of the semicircle. (TI 8 marks)
