    Rotational Inertia in two cylinders

    Calculate the kinetic energies of two uniform solid cylinders, each rotating about its central axis. They have the same mass, 1.25 kg, and rotate with the same angular velocity, 235 rad/s, but the first has a radius of 0.18 m and the second a radius of 0.73 m. I got 12112188.868 for ω, and...

    Elastic Collision: Find Velocity of 2 Bodies

    I have to stop working for now, so I don't want to make you wait for nothing. You have helped with what you told me though, so thanks for that.

    Elastic Collision: Find Velocity of 2 Bodies

    At the beginning, I believe it has GPE, and when it hits it has KE, but i don't know how to find the initial velocity. I have been looking over my notes from class for quite some time, but I am just not seeing the right equations. Could you give me a bit of a hint?

    Elastic Collision: Find Velocity of 2 Bodies

    1. A steel ball of mass 0.400 kg is fastened to a cord 60.0 cm long and fixed at the far end, and is released when the cord is horizontal. At the bottom of its path, the ball strikes a 2.00 kg steel block initially at rest on a frictionless surface. The collision is elastic. Assuming the...
