Question:

Equipment to be used in airplanes or spacecraft is often subjected to a shake test to be sure it can withstand the vibrations that may be encountered during flight. A radio receiver of mass 5.24 kg is set on a platform that vibrates in SHM at 120 Hz and with a maximum acceleration of 98 m/s 2 (=10g). Find the radio's
(a) Maximum displacement,
(b) Maximum speed, and
(c) The maximum net force exerted on it.
