Equipment to be used in airplanes or spacecraft is often subjectedto a shake test to be sure it can withstand the vibrations that maybe encountered during flight. A radio receiver of mass 5.21 kg is set on a platform that vibrates in SHMat 112 Hz and with a maximumacceleration of 91 m/s2 (=9.3 g).
(a) Find the radio's maximum displacement.
m
(b) Find the radio's maximum speed.
m/s
(c) Find the maximum net force exerted on it.
