A child rolls a basketball of mass 0.650 kg up a long ramp. The basketball can beconsidered a thin-walled hollow sphere. When the child releases thebasketball at the bottom of the ramp, it has a speed of 8.60 m/s. When the ball returns to her afterrolling up the ramp and then rolling back down, it has a speed of 3.70 m/s . Assume the work done by frictionon the basketball is the same when the ball moves up or down theramp and that the basketball rolls without slipping.
Find the maximum vertical height increase of the ball as it rollsup the ramp.
