A 20 kg child on a 2.3 m long swing is releasedfrom rest when the swing supports make anangle of 32◦with the vertical.The acceleration of gravity is 9.8 m/s2.If the speed of the child at the lowest po-yorgova (vy523) – Work and Energy B – clancy – (SCI401-2) 2sition is 2.34094 m/s, what is the mechanical energy dissipated by the various resistiveforces (e.g. friction, etc.)?Answer in units of J.
