Reference no: EM13559452

A 25 kg child on a swing 2m long is released from rest whenthe swing supports make an angle of 30 degrees with thevertical.

a) Neglecting friction, find the child's speed at the lowest position of the swing.

b) If the speed of the child at the lowest position is only2m/s, what is the energy loss due to friction?
