To reach the rack, the ball rolls up a ramp that rises through a vertical distance of h = 0.572 m. What is the linear speed of the ball when it reaches the top of the ramp?

KE= KE(transl) +KE(rot) =

=m•v²/2+Iω²/2=

= m•v²/2+ (2mR²)• v²/5•2•R²=

= m•v²/2+ mv²/5 =0.7 mv²

0.7•m•v²=mgh

v=sqrt(g•h/0.7)
