A uniform, solid sphere of radius 4.50 cm and mass 2.25 kg starts with a purely translational speed of 1.25 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 22.0∘ with respect to the horizontal. Assuming the sphere rolls without slipping down the incline, calculate the sphere's final translational speed ?2 at the bottom of the ramp.

?2=__________ m/s
