# What are some examples of a coefficient of restitution?

##### 1 Answer

Golf ball, coefficient of restitution = 0.86, steel ball bearing, coefficient of restitution = 0.60.

#### Explanation:

Golf ball, coefficient of restitution,

(where

You can also derive an expression for

(H is height of drop, h is height of rebound).

For the **golf ball** we can collect the following data:

H = 92 cm.

Find the average rebound height and then calculate the coefficient of restitution.

For the **ball bearing** we can collect the following data:

H = 92 cm.

Perform the same method as for the golf ball above.
