Find the acceleration of the wedge. (ii) A small smooth sphere moves on a horizontal floor with speed 3u. It strikes an identical sphere lying at rest on the floor, at a distance 1 metre from a vertical wall, the impact being along the line of centres and perpendicular to the wall. The coefficient of restitution for all collisions and impacts is e. (a) Find in terms of e: (i) (ii) (iii) the speeds of the spheres after the first collision the distance between the spheres when the second sphere hits the wall. the distance from tne wall at which the next collision takes place. (Ь) A smooth sphere P of mass 3 kg is moving on a smooth horizontal surface with velocity 57 + 27 m s. Another smooth sphere Q of mass 7kg is moving on the same surface with velocity 27 – 4j m s. The spheres collide when their line of centres is parallel to the 7-axis. The coefficient 7 kg of restitution between the spheres is . 3 kg Find: the velocities of both spheres after the impact to the nearest degree, the angle through which the direction of motion of P is deflected by the collision.
