At the moment when a shotputter releases a 5.00 kg shot, the shot is 3.00 m above the ground and
travelling at 15.0 m/s. It reaches a maximum height of 8.00 m above the ground and then falls to
the ground. If air resistance is negligible,
(a) What was the potential energy of the shot as it left the hand relative to the
ground?
(b) What was the kinetic energy of the shot as it left the hand?
(C) What was the total energy of the shot as it left the hand?
(d) What was the total energy of the shot as it reached its maximum height?
(e) What was the potential energy of the shot at its maximum height?
(1) What was the kinetic energy of the shot at its maximum height?
(g) What was the kinetic energy of the shot just as it struck the ground?

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.
