A person normally weighing 50kg stands on a massless platform which oscillates up and down harmonically at a frequency of 2.0 s^(-1) and an amplitude 5.0 cm. A weighing machine on the platform gives the persons weight against time. Will there be any change in weight of the body, during the oscillation?

1.	A person normally weighing 50kg stands on a massless platform which oscillates up and down harmonically at a frequency of 2.0 s^(-1) and an amplitude 5.0 cm. A weighing machine on the platform gives the persons weight against time. Will there be any change in weight of the body, during the oscillation?
Answer» SOLUTION :Here, oscillations are PERIODIC HENCE acceleration changes. The weight of MAN depend on direction of acceleration and its magnitude in up and down motion. (a) Hence, weight of man changes during oscillations.
