I've got these questions to do, and I've looked at the formulas and can't seem to plug in the numbers with the values I've been given. I think I'm missing something somewhere, if someone could just start me off, or be so kind as to go through the method so I know for the future?

Thank you :)

a) A wheel rolls up an incline of 15 degrees on its hubs without slipping and is pulled by the 100N force applied to the cord wrapped around its outer rim. The wheel starts from rest, so compute its angular velocity after its center has moved a distance of 3m up the incline. Radius to inner rim is 100mm, radius to outer rim 200mm.

b) The wheel has a mass of 40 kg with center of mass at O and has a centroidal radius of gyration of 150mm. Determine the power input from the 100N force at the end of the 3m motion interval.
