3. The figure below shows various positions of a child on a swing moving toward Mr. Doig on the ground blowing a 3-kHz whistle. If the child starts from rest at Point A a height 0.75 m above the ground, calculate the frequency the child hears at Points A, C, and E, on the swing forward. Additionally, calcu- late the frequency the child hears at Point C on the swing back. When does the child hear the highest pitch? Hint: you might want to use energy conservation. Here are some equations from a past unit: KE = mv² and PE = mgh. B D Whistle Whistle E
