A body of mass 4 kg is executing shm of amplitude 0.4 m and period 2 s. Find (i) the maximum restoring force and (ii) the restoring force at a distance of 0.1 m from extreme position.

A body of mass 4 kg is executing shm of amplitude 0.4 m and period 2 s

1.	A body of mass 4 kg is executing shm of amplitude 0.4 m and period 2 s. Find (i) the maximum restoring force and (ii) the restoring force at a distance of 0.1 m from extreme position.
Answer» SOLUTION :(i) `F_(MAX)=momega^2a=4xx(2pixx2)^2xx0.4=15.78 N`(II) `F = momega^2y=4 xxpi^2xx(0.4-0.1) = 11.84 N`
