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
