A clock is performing SHM along a vertical line with amplitude of 40 cm on a horizontal plank. The block just lose the contact with plank when plank is momentarily at rest. Then, (Take, `g=10m//s^(2)`)

A horizontal plank has a rectangular block placed on it. The plank starts oscillating vertically and simple harmonically with an amplitude of 40 cm. The block just loses contact with the plank when the latter is at momentary rest Then.

A plank with a bar placed on it performs horizontal harmonic oscillations with amplitude a=10cm . Find the coefficient of friction between the bar and the plank if the former starts sliding along the plank when the amplitude of oscillation of the plank becomes less than T=1.0 s .
