Question

What best describes the dropping height of a ball that bounced back up to a height of 45 centimeters

A. Less than 45 cm, as the ball transforms some of its thermal energy into potential energy
B. Greater than 45 cm, as the ball transform some of its thermal energy into potential energy
C. Less than 45 cm, as the ball transforms some of its potential energy into thermal energy and sound energy
D. Greater than 45 cm, as the ball transforms some of its potential energy into thermal energy and sound energy

Answer 1

C) Less than 45 cm, as the ball transforms some of its potential energy into thermal energy and sound energy

Step-by-step explanation:

The ball will transform some of it's potential energy into sound energy, which is why you will hear a noise once it has hit the ground.

Answer 2

I would say B 'cause it wouldnt need sound energy so its not C or D and it needs more potential energy to bounce and stuffs...

The answer is B, if im wrong, SORRY
