It is required to determine the coordinates of the Centre of Mass of the Lamina shown in Figure 5 below. The missing portion BEDB from the Lamina is a semi-circle of radius 3 units centred at C. The arc DF is a quarter-circle centred at B. FG=EC=3 units AG=2 units A 3 F CO 3 E С D Figure 5 (5 marks
Question 8 (4 marks) A sphere, A, of mass, me= 3m is moving with an initial speed, ua = 2u on a smooth horizontal surface. The sphere A collides with another sphere B of mass, mi = 2m travelling in the opposite direction to A, with initial speed, us=u. After the collision sphere A continues to move in the same direction with speed, u Va Find: a) The speed of sphere B after the collision. (2 marks) b) The coefficient of restitution between spheres A and B. (2 marks)
