Auniform, solid sphere of radius 4.00 cm and mass 3.75 kg starts with a purely translational speed of 3.75 m/s at the top of an inclined plane. the surface of the incline is 2.75 m long, and is tilted at an angle of 30.0∘ with respect to the horizontal. assuming the sphere rolls without slipping down the incline, calculate the sphere's final translational speed v2 at the bottom of the ramp.
