Asled of mass m starts from rest at the top of a hemispherical frictionless hill of radius r.
a) use conservation of mechanical energy to find an expression for the sled’s speed when it is at an angle ∅.
b) use newton’s 2nd law and ideas of circular motion to find the maximum speed the sled can have at angle without leaving the surface.
c) at what angle ∅_max does the sled "fly off" the hill?
