Atennis ball bounces on the floor three times. if each time it loses 11% of its energy due to heating, how high does it rise after the third bounce, provided we released it 4.4 m from the floor?

h = 3.10 m

Explanation:

As we know that after each bounce it will lose its 11% of energy

So remaining energy after each bounce is 89%

so let say its initial energy is E

so after first bounce the energy is

after 2nd bounce the energy is

After third bounce the energy is

here initial energy is given as

now let say final height is "h" so after third bounce the energy is given as

now from above equation we have

this is a good question! i'll do some research and come back when i have the answer!
