9) A ball of mass m is attached to the ceiling via a string of length L. The ball is given a push to set it in motion. The ball then travels in a horizontal circle, such that the string makes and angle 0 with the vertical. It is observed that it takes time T for the ball to make one complete revolution. How can this experiment be used to measure the magnitude of the gravitational acceleration g. problem 9...

A tether ball is attached to a swivel in the ceiling by a light cord of length L. When the ball is hit by a paddle, it swings in a horizontal circle with constant speed v, and the cord makes a constant angle beta with the vertical direction. The ball goes through one revolution in time T. Assume that T, the mass m, and the length L of rope are known, derive algebraic expression for the tension FT in the...

A ball moves in a vertical circle attached to a light string of length 0.3 m fixed at its center. Assume that the only force acting on the ball are its weight and the tension of the string. Determine the minimum speed the ball must have, when the string makes a 90 degree angle with the vertical, so as to complete the circle by reaching the top.

20> A 5.15 kg ball is attached to the top of a vertical pole with a 2.29 m length of massless string. The ball is struck, causing it to revolve around the pole at a speed of 4.41 m/s in a horizontal circle with the string remaining taut. Calculate the angle, between 0° and 90°, that the string makes with the pole. Take g 9.81 m/s2. angle: What is the tension of the string? tension: N

Consider a mass m which is attached to the origin by a rope of length R, and is free to swing under the influence of gravity. In other words, it is constrained to be on the inside surface of a frictionless sphere of radius R. Find the equations of motion, denoting θ as the angle that the rope makes with the vertical (θ = 0 is straight down) and φ as the normal angle in the xy plane.
