A disk with a c value of ½, a mass of 3 kg, and radius of 0.34 meters, rolls without slipping down an incline which has a length of 7 meters and angle of 30 degrees. At the top of the incline, the disk is spinning at 29 rad/s. How fast is the disk moving (center of mass) at the top of the incline in m/s?

Answer #1

Hi ....Dear I think it should be asked in the problem to find the speed at the bottom because the linear velocity can be simply calculated by v0 = 0.34 * 29

But I have calculated the bottom velocity as well.If you have any confusion then please ask me in the comment box.
