3. A 50.0-kg child on a 2.0 m long swing is released from rest when the swing supports make an angle of 30 degrees with the vertical.

a. What are the potential and kinetic energies of the child before being released?

b. Neglecting friction, what are the potential and kinetic energies of the child at the lowest position?

c. Find the child's speed at the lowest position

d. If the speed of the child at the lowest position is 0.10 m/s, what is the mechanical energy lost due to friction?
