Problem

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

s. Taking acceleration due to gravity,

g = 10\,\text{m/s}^2

, the maximum variation of the object's weight (in N) as observed in the experiment is _____
