Question:

A roller coaster starts from rest at A, rolls down the track to B, describes a circular loop of 40-ft diameter, and moves up and down past Point E. Knowing that h = 60 ft and assuming no energy loss due to friction,

A roller coaster starts from rest at A, rolls down

Determine
(a) The force exerted by his seat on a 160-lb rider at B and D,
(b) The minimum value of the radius of curvature at E if the roller coaster is not to leave the track at that point.
