A 10.0-kg cylinder rolls without slipping on a rough surface. At the instant its center of amss has a speed of 10m/s, determine (a) the translational kinetic of its center of mass (b) the rotational kinetic energy about its center of mass and (c) its total kinetic energy.
can u check if this is the correct answer?
please tell me if that is correct ornot XD thanks
^please check that work i have shown above thanks
this is correct
wrong wrong wrong ..... you need to start reading before you try plugging numbers in like an accountant with a nearing deadline, son ........
According to my physics book with the answers in the back, this is correct.
why are you using .25 for b??
cyndi used 1/4 because of this:
as you can see the radii cancel and the 1/2's multiply together to make 1/4
