Textbook Problem

A slingshot consists of a light leather cup containing a stone. The cup is pulled back against two parallel rubber bands. It takes a force of 15.0 N to stretch either one of these bands 1.00 cm. (a) What is the potential energy stored in the two bands together when a 50.0-g stone is placed in the cup and pulled back 0.200 m from the equilibrium position? (b) With what speed does the stone leave the slingshot?

a)

To determine
The potential energy stored.

Explanation

Given info: The force required to stretch either of the rubber bands to 1.00cm is 15.0N . The mass of the stone placed in the cup is 50.0g and is pulled by 0.200m .

Explanation:

The force constant of each band is given by,

k=Fx

Here,

F is the restoring force on the block

k is force constant of the spring

x is the displacement of the spring

Substitute 15.0N for F , 1.00cm for x to find the force constant.

k=15.0N1.00cm=15.0N1.00×102m=1

b)

To determine
The speed of the block as it passes through the equilibrium.
