A motorcycle has a constant speed of 24.0 m/s as it passes over the top of a hill whose radius of curvature is 123 m. The mass of the motorcycle and driver is 337 kg. Find the magnitude of(a) the centripetal force and(b) the normal force that acts on the cycle.

Question

anonymous · Answer

F = [mv^{2}] / r
   = [337 X (24)^2] / 123
   = 1578.14 N
Normal force depends on where the motorcycle is.

it says at the top

at the top, 

Its zero I think.

anonymous · Answer

Because centripetal force = gravity and they cancel out hence causing no movement in the y-direction.
