Question

A 40-kg child slides down a curved slide starting at the top with an initial speed of 4 m/s.

(a) Suppose that the slide is frictionless. Determine the speed of the child when she is 3 m below her starting height.
(b) Suppose that the slide has friction. Determine the speed of the child when she is 5 m below her starting height if she starts from rest and 300 J of thermal energy is dissipated during the motion.
