Question

Problem 17

Answer 1

Given information

As the child moves from point A to point E, the child's initial velocity toward man will be zero at point A, and it will be maximal at point C, which has the lowest potential energy and highest frequency.

Step-by-step explanation

Step 1.

While the youngster is swinging forward, the maximum frequency of sound will be heard at position C. If the child is traveling with SHM, the highest speed is at point C, which is the equilibrium point. In order to have a higher pitch, the source and detector must be moving in the same direction.
