Q1. A uniform solid disk with the mass of 33.50 kg and a radius of 0.318 m is free to rotate about a frictionless axle. Forces of 90.0 and 125 N are applied to the disk. Taking the clockwise direction to be the negative direction, what is (a) net torque produced by the two forces and (b) angular acceleration of the disk?
Q2. A shell of mass m and speed v explodes into two identical fragments. If the shell was moving horizontally (the positive x direction) with respect to Earth, and one of the fragments is subsequently moving vertically with speed v, find out the velocity ' of the other fragment immediately following the explosion.
