A uniform rod of length 1.4 m is attached to a frictionless pivot at one end. It is released from rest from an angle θ = 23° above the horizontal. Find the magnitude of the initial acceleration of the rod's CM.
At = alpha * r
The Attempt at a Solution
I am reviewing old homework problems for my test tomorrow so I just have a few questions....
What is CM?
Also is At known as initial acceleration not Ac?
