Q7). A soft tennis ball is dropped onto a hard floor from a height of 2,85 m and rebounds back to a height of 2.25 m above the floor. Gravity = 10 m/s2 and assume no loss of energy. a). b). c). d). Calculate its velocity just before it strikes the floor Calculate its acceleration during contact with the floor if that contact lasts 2.60 ms How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid? Draw a detailed diagram of the situation
