A father places his daughter in a swing that is 0.60 m above ground. Then he raises the swing to a height of 1.5 m and lets go. The girl and the swing have a combined mass of 16 kg. Assume friction is negligible and use g=9.8m/s^2. a) Draw a sketch of the scenario.  b) Determine the PE of the girl after the swing has been raised to the 1.5 m height.  c) Calculate the girl’s fastest speed. Round your answer to the nearest tenth.
