here's a tough one :S
A 70kg person rides in a 30kg cart moving at 12 m/s at the top of the hill that is the shape of an arc of a circle with radius of 40m.
a) What is the apparent weight of the person as the cart passes over the top of the hill?
b) Determine the maximum speed that the cart may travel at the top of the hill without losing contact with the surface. Does this depend on the mass of the cart or that of the person?
help!
