Question

Greg decides to use his physics expertise to open a new amusement park. He creates a ride in which a car
with two riders is initially pushed up against a spring (k = 30,000 N/m), compressing it by 2 m. The car then
goes up a ramp which is frictionless except for the 2.5 meter patch shown. Next the car goes through a loop-
de-loop and is eventually shot straight up into the air before coming back down onto the track. Cool, eh?

What is the magnitude of the normal force exerted by the track on the 300-kg car
(including riders) at point B, at the top of the loop-de-loop? (Remember, the speed of
the car at point B is 10 m/s.)
