## Homework Statement

A wrecking ball swings at the end of a 10.0-m cable on a

vertical circular arc. The crane operator manages to give the ball a

speed of 6.00 m/s as the ball passes through the lowest point of its

swing and then gives the ball no further assistance. Friction and

air resistance are negligible. What speed v does the ball have

when the cable makes an angle of 30.0° with respect to the

vertical?

## Homework Equations

Gravitational potential energy

## The Attempt at a Solution

The answer must be 3.1 m/s
