Asolid sphere of mass 2.50 kg and radius 0.120 m starts from rest at the top of a ramp inclined 15.0° and rolls to the bottom. the upper end of the ramp is 1.60 m higher than the lower end. what is the linear speed of the sphere when it reaches the bottom of the ramp? (note: i = mr2 for a solid sphere, and g = 9.80 m/s2.)
