Auniform solid sphere is rolling without slipping along a horizontal surface with a speed of 5.50 m/s when it starts up a ramp that makes an angle of 25.0° with the horizontal. what is the speed of the sphere after it has rolled 3.00 m up the ramp, measured along the surface of the ramp?

This question can be answered using the conservation of energy.

Explanation:

The moment of inertia of a solid sphere is

The potential energy is found by using the vertical distance, not the 3.00 m up the ramp. We multiply this 3.00 m by sine of 25° to find the vertical distance.

In rolling without slipping the translational speed is related to rotational speed through .

the answer is b i think
