In the arrangement shown below, an object can be hung from a string (with linear mass density μ = 0.00200 kg/m) that passes over a light pulley. The string is connected to a vibrator (of constant frequency f), and the length of the string between point P and the pulley is L = 2.30 m. When the mass m of the object is either 25.0 kg or 36.0 kg, standing waves are observed; no standing waves are observed with any...

A pendulum consists of a small object hanging from the ceiling at the end of a string of negligible mass. The string has a length of 0.78 m. With the string hanging vertically, the object is given an initial velocity of 2.9 m/s parallel to the ground and swings upward in a circular arc. Eventually, the object comes to a momentary halt at a point where the string makes an angle θ with its initial vertical orientation and then swings...

1. For a stationary ball of mass m = 0.200 kg hanging from a massless string, draw arrows (click on the “Shapes” tab) showing the forces acting on the ball (lengths can be arbitrary, but get the relative lengths of each force roughly correct). For this case of zero acceleration, use Newton’s 2nd law to find the magnitude of the tension force in the string, in units of Newtons. Since we will be considering motion in the horizontal xy plane,...

(a) An elevator of mass m moving upward has two forces acting on it: the upward force of tension in the cable and the downward force due to gravity. When the elevator is accelerating upward, which is greater, T or w? (b) When the elevator is moving at a constant velocity upward, which is greater, T or w? (c) When the elevator is moving upward, but the acceleration is downward, which is greater, T or w? (d) Let the elevator...

1. An object of mass 1.2 kg is attached to a string of 0.83 m. When this object is rotated around a horizontal circle, it completes 15 revolutions in 9.6 seconds. a. What is the period (T) of this motion? b. What is the tangential velocity of the object? c. What is the tension on the string? Hint: The tension on the string is the centripetal force that causes the circular motion.
