A ball of mass 1.2kg and a volume of 35cm cubed is dropped from a height of 2m. Determine the height to which this ball will bounce.

• physics -

If the collision with the ground is perfectly elastic it will bounce back up to 2m. Otherwise you have to know how squishy the collision was.

• physics -

The density of the ball, 34 g/cm^3, is higher than that of any known material outside a star. Even uranium has a density about half that.

Did you make up that question? Perhaps someone is playing a practical joke with this question.

If you dropped that ball on concrete, it would probably leave send pieces of concrete flying, leave a crater, and bounce poorly.

• physics -

drwls- so the answer cannot be determined?

• physics -

Correct. An experiment would be needed to establish the fractional energy loss per bounce.
