Two identical balls undergo collision as shown in the diagram. Ball 1 is initially travelling at 4 m/s towards Ball 2 initially at rest. After the collision, Ball 1 moves away with a velocity of Vf? at an angle, d, of 45.9° below the surface from the original path and Ball 2 moves away with a velocity of V?2 at an angle, 0 of 25.5° above the horizontal. a) b) 1 V? = 4 m/s Viz =0 m/s 2 Before Collision 2 0=25.5° $=45.9° f? After Collision 182 Calculate the total momentum before collision. Calculate the vf? and Vf2. [2 marks] [4 marks]
