A wrecking ball swings at the end of a 11.5-m cable on a verticalcircular arc. The crane operator manages to give the ball a speedof 4.75 m/s as the ball passes through the lowest point of itsswing, and then gives the ball no further assistance. Friction andair resistance are negligible. What speed vf does the ball havewhen the cable makes an angle of 18.0° with respect to thevertical?
m/s
Please explain, thanks
