A light rope was wrapped around the cylinder, which can freely rotate around the axis passing through its center
with mass Mand radius R, and passed over a pulley, which is considered to be massless and frictionless, and a mass
of 4m was attached to its end and the system was released from the height h from rest. What is the speed of a 4m
object when it hits the ground? (nder =Mr?)
While spinning down from 500.0 rpm to rest, a solid uniform disk does 51 KJ of
work. If the radius of the disk is r=400mm what is it's mass?.
Current Attempt in Progress
The figure shows a thin rod, of length L = 1.50 m and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy
ball of mass m = 8.90 kg is attached to the other end. The rod is pulled aside to angle 80 = 17° and released with initial velocity Vo = 0.

Hint: You don't have any details about the time while the car is going down the hill or through the loop, so you don't know how fast it is going at the top of the loop.arrow_forward
