A solid sphere of mass 0.595 kg rolls without slipping along a horizontal surface with a translational speed of 5.16 m/s. It comes to an incline that makes an angle of 36 with the horizontal surface. Neglecting energy losses due to friction,

(a) what is the total energy of the rolling sphere?

Im pretty sure that this is a total of the trans. velocity and rotational velocity but I dont know how to get the rotational velocity from the information given.

(b) to what vertical height above the horizontal surface does the sphere rise on the incline?
