A wrecking ball swings at the end of a 11.4-m cable on averticalcircular arc. The crane operator manages to give the ball aspeedof 12.0 m/s as the ball passes through the lowest point ofitsswing and then gives the ball no further assistance. Frictionandair resistance are negligible. Whatspeed vfdoes the ball have when thecable makes an angle of 26.9 ° withrespect to the vertical?
