Question

A uniform solid sphere is rolling without slipping along a horizontal surface with a speed of 1.36 m/s when it starts up a ramp that makes an angle of 19.1 degrees with the horizontal. What is the speed of the sphere (in m/s) after it has rolled 0.306 m up the ramp, measured along the surface of the ramp?
