QUESTION #47 Impulse and Momentum
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 g = 9.8 mathrm~m / s^2)

QUESTION #58 Conservation of Angular Momentum
Consider a Disc of mass 5 mathrm~kg, radius 2 mathrm~m, rotating with angular velocity of 10 mathrm~rad/s about an axis perpendicular to the plane of rotation. An identical disc is kept gently over the rotating disc along the same axis. The energy dissipated so that both the discs continue to rotate together without slipping is ________ J. {{IMG1}}
