A very light (meaning don't consider mass of the rod) rod is placed along the x axis. It has a mass m1=2.0kg at x=0, a mass m2=1.50kg at x=50cm, and a mass m3=3.0kg at x=100cm.
Find the moment of inertia of the system about a pivot point at x=0.
A bullet of mass m and speed v passes completely through a pendulum bob of mass M. The bullet emerges with a speed of v/2. The pendulum bob is suspended by a stiff rod of length L and negligible mass.
What is the minimum value of v such that the pendulum bob will barely...
[SOLVED] Center of Mass of an irregularly shaped object
A uniform piece of sheet steel is shaped as shown:
Compute the x and y coordinates of the center of mass of the piece.
The sketch above isn't very good but its a graph with an X and Y...
