A light rod of length / is pivoted at the upper end. A point mass m is attached at the free end of the rod. What horizontal velocity must be imparted to the lower end mass, so that tension in the rod is 2mg when it is at the topmost position?
Added by Allen P.
Step 1
Draw a diagram of the situation. The rod is pivoted at the upper end, and a point mass m is attached at the free end. The rod is initially at the topmost position, and we want to find the horizontal velocity required to maintain a tension of 2mg in the rod. Show more…

A rigid rod of mass M and length L is pivoted around point P at one of its ends (see figure below). Find the speed of the center of mass of the rod when it is vertical if it is released from its horizontal position. (Use any variable or symbol stated above along with the following as necessary: g. Do not substitute numerical values; use variables only.)

A uniform rod of length $L$ and mass $M$ is held vertically with one end resting on the floor as shown below. When the rod is released, it rotates around its lower end until it hits the floor. Assuming the lower end of the rod does not slip, what is the linear velocity of the upper end when it hits the floor?
