Does this question involve the velocity of the oscillator at all? I think it is simply asking for the wave being emitted by the heart wall of the unborn chimp. There is more to this question later on about applying the Doppler effect to find the change in frequency measured by the ultrasonic...
This was the only information given in the problem.
As for SHM, I know that the maximum velocity of a point on the wave occurs at the moment of equilibrium because of transfers of energy. I do have an equation maximum kinetic energy. E(mech) = (1/2) k A^2 = U(s, max), but I don't know how...
Homework Statement
A vet is using an ultrasonic motion detector to detect the heartbeat of an unborn chimp baby and claims that the speed of sound in the soft tissue of a chimp should be 1489 m/s. According to the manual which comes with the motion detector, the emitted frequency of sound...
