A basketball is dropped from a height of 2.00 meters above the ground. On the first bounce the ball reaches a maximum height of 1.10 meters where it is caught. Find the velocity of the ball:

a.

just before it makes contact with the ground

b.

just after it leaves the ground after the bounce

And, just for fun, how much energy is lost during the bounce? Assume the ball weighs 0.2 kg.

• Hint
• Solution: part a.
• Solution: part b.
• Solution: part c.
• Solution: part d.
