A0.70-kg basketball dropped on a hardwood floor rises back up to 65% of its original height. (a) if the basketball is dropped from a height of 1.5 m, how much energy is dissipated in the first bounce? (b) how much energy is dissipated in the fourth bounce? (c) to which type of incoherent energy is the dissipated energy converted?

Part a)

Part b)

Part C)

This is loss in terms of thermal energy due to collision with the floor

Explanation:

Part a)

Since we know that the ball rises up by 65% of initial height

so after first bounce it will lose 35% of its initial energy

so we will have

Energy Loss = 0.35 mgH[/tex]

Part b)

Energy of the ball after first bounce

energy of ball after 2nd Bounce

energy of the ball after 3rd bounce

Now we will have energy loss in fourth bounce given as

Part C)

This is loss in terms of thermal energy due to collision with the floor

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

pe = weightxheight = 2000x1000=2,000,000joules
