Q1: An object is attached to a pendulum whose string length is 4 meters. If the ideal pendulum (neglect the mass of the string and the shape of the object) is displaced by an angle of 20 degree with respect to the vertical, and released from rest, what is its speed at its lowest location?
A pendulum consists of a mass m suspended from a string of length L. When the pendulum is swinging, how much greater is the mass’s potential energy when the string is displaced from the vertical by the angle θ than when the mass is at the lowest position?
Part 1: (Theory) Simple Pendulum 1. Consider a mass m hanging from a string of length L that makes an angle with the vertical (shown below). Assume the string is massless and that the hanging object is a point mass. Use Newton's Second Law directly to show that the equation of motion for this simple pendulum can be written: (LO) = -mgsin(o), (1) dia where is the angular displacement of the pendulum from its vertical equilibrium position (and is a...

There is a pendulum made of a uniform rod of mass 'M' and length 'l'. Let theta be the angle between the pendulum and the vertical axis. It is raised to the right to an angle thetao. It is then released from rest and at its lowest point (theta=0), it elastically collides with a mass 'm'. Consider the table to be frictionless. What is the velocity of the mass and the angular speed of the pendulum after the collision?
he length of a simple pendulum is 0.65 m and the mass of the particle (the “bob”) at the end of the cable is 0.20 kg. The pendulum is pulled away from its equilibrium position by an angle of 7.7° and released from rest. Assume that friction can be neglected and that the resulting oscillatory motion is simple harmonic motion. (a) What is the angular frequency of the motion? (b) Using the position of the bob at its lowest point...

A simple pendulum consists of a ball of mass M hanging from a uniform string of mass m and length L, with m << M. (a) If the period of oscillations for the pendulum is T, derive an expression for the speed of a transverse wave in the string when the pendulum hangs at rest in terms of m, M, T and g (the acceleration due to gravity). Your expression should not include L. (b) If the string is made...
