A bicycle wheel is rolled down a hill that is 8 m high, Determine the linear speed of the wheel at the bottom of the hill if the wheel is moving initially at .5 m/s I= 1/2mr^2 mgh=1/2mv^2 I know it is set up like a KE equation, and I also know I am missing a variable to solve for...

Thanks so much! I will be working on this later on today, I will let you know if I have anymore questions

Thank you so much! I will let you know if I have anymore questions later on.

A stationary wheel ?(solid cylinder) of radius .3m and mass of 1.75 kg has a 12 Nm torque applied to it. Determine the frequency of the wheel after 15 seconds. I = 1/2mr^2 Am I supposed to find "I" first? What is the best way to go about this problem?

From the diagram above, solve for the reaction at point A. and the tension in the cable that is attatched at point C. Assume the bar is mass-less. Block B has a mass of 124 kg. The distance from point B to point A is 3.2m, from point A to point D is 1.3 m, and point D to point C 2.1 m. The cable...
