A mass
m is undergoing SHM in the vertical direction about the mean position
y0 with amplitude A and angular frequency
ω. At a distance
y from the mean position, the mass detaches from the spring. Assume that the spring contracts and does not obstruct the motion of
m. Find the distance
y∗ (measured from the mean position) such that the height
h attained by the block is maximum.
