Center Of Mass

A spherical body of mass \(100 \mathrm{~g}\) is dropped from a height of \(10 \mathrm{~m}\) from the ground. After hitting the ground, the body rebounds to a height of \(5 \mathrm{~m}\). The impulse of force imparted by the ground to the body is given by : (given, \(\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^2\))
