1.	A solid sphere of 1kg reaches the bottom of an inclined plane after rolling without slipping over a horizontal plane with velocity of 20ms^(-1). The inclination of the plane with the horizontal is 30^(@). What is the velocity of the center of mass of the sphere immediately after it starts moving up the plane? Up to what distance along the plane will it rise? Assume sufficient friction to prevent slipping.
