A pendulum swings back and forth. The pendulum is a one-dimensional rod that is connected to a disk. The length of the rod is L and the radius of the disk is R. The mass of each object is M0.
At this point, we know: M0, L, R, and g
Part A: What is the angular acceleration of the swinging pendulum when it at angle θ relative to vertical? Counterclockwise is the positive direction. Answer in known quantities and simplify your answer.

A spider of mass m is swinging back and forth at the end of a strand of silk of length L. During the spider's swing the strand makes a maximum angle of θ with the vertical. What is the speed of the spider at the low point of its motion, when the strand of silk is vertical? Express your answer in terms of the variables m, θ, L, and g.

Conical Pendulum A mass attached at the end of a massless string swings around in a horizontal circle (the string sweeps out a cone). Let θ be the angle the string makes with the vertical, l be the length of the string, h is the vertical height of the string, and r is the radius of the circle. So, l is the hypotenuse of a right triangle with h and r as legs, and θ as the upper angle. The...

A small object oscillates back and forth at the bottom of a frictionless hemispherical bowl, as the drawing illustrates. The radius of the bowl is R, and the angle is small enough that the object oscillates in simple harmonic motion. Derive an expression for the angular frequency w of the motion. Express your answer in terms of R and g, the magnitude of the acceleration due to gravity. Hemispherical bowl R

The pendulum shown below consists of a slender rod of length L and a think disk of radius r. If the rope connected to the disk breaks as shown, find the initial angular accleration of pendulum and the reaction forces at O.

The period of a pendulum (i.e. the time it takes to swing back and forth over one cycle of motion) can credibly be believed to depend on both the length of the pendulum and the acceleration due to gravity. We can write this as Where C is some unknown constant, L is the length of the pendulum, g is the acceleratio lue to gravity, and x and y are unknown. Using dimensional analysis, determine how T lepends on L and...
