## 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 $5.24 \mathrm{kg}$ is set on a platform that vibrates in SHM at $120 \mathrm{Hz}$ and with a maximum acceleration of $98 \mathrm{m} / \mathrm{s}^{2}(=10 g) .$ Find the radio's (a) maximum displacement, (b) maximum speed, and (c) the maximum net force exerted on it.
