Question

A uniform, solid sphere of radius 3.50 cm and mass 1.25 kg starts with a purely translational speed of 2.50 m/s at the top of an inclined plane. The surface of the incline is 1.50 m long, and is tilted at an angle of 28.0∘ 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

Answer 1

Here,

u= 2.50 m/s

s= 1.50 m

Then,
