1. Define the following terms: (a) linear momentum; (b) angular momentum; (c) moment of force. A uniform circular disc of mass M and radius R is mounted, that it can turn freely about its center, which is fixed. It is spinning with angular velocity w about the perpendicular to its plane at the center, the plane being horizontal. A particle of mass m, falling vertically, hits the disc near the edge and adheres to it. Prove that immediately afterwards the particle is moving in a direction inclined to the horizontal at an angle a given by the equation 4m(M +2m) tana = M(M + 4m) where v is the speed of the particle just before impact and w= WI. 5) Go).
