a. When the displacement in SHM is 0.2 the amplitude A, what fraction of the total energy is kinetic energy?
b. What fraction of total energy is potential energy?
c. At what displacement, in terms of the amplitude, is the energy of the system half kinetic energy and half potential energy?
For a rough calculation, we shall assume that the doctor is 50 from the baby (she is likely to be even closer at delivery), has a mass of 75.00, and can be modelled as a uniform sphere.
