[SOLVED] Rotational Motion (Inclined Plane)
Hi Everyone!
My question is: A solid cylinder and a solid sphere are resting on top of a inclined plane. Using mathematics, which object would reach the ground first. Given: I (cylinder) = 1/2mr ^2 and I (sphere) = 2/5 mr ^2.
I know that the...
I don't really know how to do that! But the vertical one is with tension going up and weight going down, the first weight is normal force going up and weight going down, and the second horizontal weight is normal force going up and weight going down. The tensions are up for the vertical weight...
