Ade anza student enters the first annual mission college student vs machine butt-kicking contest. the machines get to go first. the machine is constructed with a boot attached to a disk (the disk's radius = r and its mass = m_d) by a massless rod (the length of the rod is 3r) to a boot with a mass m_b (you can treat it as a point mass at the end of the rod). a) what is the moment of inertia of boot-disk system? b) what is the torque produced by the hanging mass? c) what's the tangential v of the boot after rotating delta theta = pi, d) what's the de anza students velocity if the boot (which is moving horizontally at the time of impact) breaks off in their butt (an inelastic collision) assuming their mass is 80xm_b?
