A uniform, solid sphere of radius 5.00 cm and mass 1.75 kgstarts with a purely translational speed of 3.25 m/s at the top of an inclined plane. The surface of the incline is 1.75 m long, and is tilted at an angle of 24.0∘with respect to the horizontal. Assuming the sphere rolls without slipping down the incline, calculate the sphere's final translational speed ?2at the bottom of the ramp.
