QUESTION NO. 6: MANDATORY/DOPTIONAL/BONUS (8 POINTS) a) A ball of mass mi= 1 kg and speed of 3 m/s collides with a ball of mass m2= 3 kg and speed of 2 m/s a time of 0.02 s. After collision, mị moves right with a speed of 1.5 m/s. Find (1) The speed of m2 after collision. (2) The force they act on each other throughout collision. m m2 m2 СМ b) The centre of mass of objects in the figure locates at x= 5m. Mass mi= 5 kg locates at x= 2m, and the second mass m2 locates at x=6 m. Determine m2. 5 6.
