Module 6 Assignment 1. An object of mass 5kg moves with a velocity of 3m/s and collides with another object of mass 6kg moving with a velocity of 5m/s in an elastic collision . calculate the speed of the first object after collision of the second object has a final speed of 4m/s. (All inclusive calculations in physics ,book 2 ,ex 6) 2. 5. A boy whose mass is 10kg stands on a spring weighing machine inside an elevator . calculate the reading on the machine when the elevator is coming to rest at a retardation of 4m/s (All inclusive calculations in physics ,book 2 ,ex 6)
3. A body of mass 7kg moving with a velocity of 15m/s collides with a body of mass 5kg moving with a velocity of 8m/s, calculate the loss in kinetic energy of the ball (All inclusive calculations in physics ,book 2 ,ex 6)
