Physics - SHM Question with Solution | TestHub

A person sitting inside an elevator performs a weighing experiment with an object of mass 50 kg . Suppose that the variation of the height $y$ (in m ) of the elevator, from the ground, with time $t$ (in s ) is given by $y=8\left[1+\sin \left(\frac{2\pi t}{T}\right)\right]$, where $T=40\pi \mathrm{s}$. Taking acceleration due to gravity, $g=10\mathrm{m}/{\mathrm{s}}^2$, the maximum variation of the object's weight (in N ) as observed in the experiment is _______ .
