34. [4 marks] A ball of mass 0.7 kg slides on a frictionless surface at a speed of 12 m/s (East) and collides with an initially stationary ball of mass 0.9 kg. After the collision, the lighter ball is deflected by an angle of 39 North of East, and the heavier ball is deflected by an angle of 25 South of East. Determine the speeds of the two balls after the collision.33. [3 marks] An object of mass 1.4 kg is attached to a vertical spring originally at rest. released1 and oscillates vertically. The object. is released from rest. at the springs original rest. length (i.e., before it. is stretched by the attached object). (a) Determine the magnitude of the force that the spring exerts on the object at its lowest point. (b) Determine the amplitude of the oscillations if the spring has a stillness constant of 157 N/m. (0) Determine the ob jeetls maximum speed. 32. [3 marks] A ball of mass 1.2 kg is thrown from the top of a tower .52 111 above the ground at an initial speed of 26 111 / 5 and at an initial angle of 310 above the horizontal. Air resistance does work of 217 J on the ball an it falls. Determine the impact speed of the ball
