    Rotational Inertia Hill Problem

    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...

    Finding frequency of rotating cylinder after torque applied for 15 seconds

    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?

    Circular Motion 12th grade physics

    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...
