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.

The velocity or speed V2 at the bottom of the ramp is

Explanation:

Calculated the velocity of the sphere at the bottom of the ramp using the law of conservation of energy

But Inertia can be use in value using in the initial equation so:

So replacing also can get factor m from all terms an eliminated 'm'

To find 'h'

learn it on the intertant so you can solve
