- A pendulum consists of a small rock hanging from a string of length 0.64-m. Pull the rock sideways and release it from rest to set the pendulum in motion. How long after releasing it does it take to attain its greatest speed the first time?A simple pendulum is made from a 0.666-m-long string and a small ball attached to its free end. After the ball is released pulled to one side through a small angle and then released from rest. After the ball is released, how much time elapses before it attains its greatest speed?The figure below shows a simple pendulum. The length of the string is l and the bob has mass mj. m. If the mass is released from rest when 0 = 75.4°, at which values of 0 does the mass have half of its maximum kinetic energy?
- A simple pendulum, consisting of a mass of 2.0 kg, is attached to the end of string with unknown length. The mass is held out horizontally, and then released from rest. What must be the length of the string (m) if the speed of the mass at the bottom of the swing is 3.3 m/s?A mother is pushing her little son, Mark, on a swing; The highest point reached by the swing is 1.0 meter and the lowest point is 0.30 meter. Find the maximum speed of Mark while riding on the swing.A 12-kg block on a horizontal frictionless surface is attached to a light spring (force constant 0.80 kN/m). The block is initially at rest at its equilibrium position when a force (magnitude P- 80 N) acting parallel to the surface is applied to the block, as shown. What is the speed of the block when it is 13 cm from its equilibrium position? a. 0.78 m/s b. 0.81 m/s c. 0.71 m/s d. 0.58 m/s e. 0.64 m/s

A simple pendulum is suspended from the ceiling by means of a string of length 1.14 m. Assume that there is no friction or air resistance. Suppose you were to release the pendulum from rest, starting from an angle of 58.2 degrees with respect to the vertical, as shown.

- You and your friends find a rope that hangs down 15 m from a high tree branch right at the edge of a river. You find that you can run, grab the rope, swing out over the river, and drop into the water. You run at 2.0 m/s and grab the rope, launching yourself out over the river. How long must you hang on if you want to drop into the water at the greatest possible distance from the edge?An ideal spring is attached to the ceiling. While the spring is held at its relaxed length, a wooden block (M = 850 g) is attached to the bottom of the spring, and a ball of clay (m = 210 g) is pressed onto the bottom of the block so that they stick together. The block+clay are gently lowered through a distance of d = 2.7 cm and are then released, at which point they hang motionlessly from the bottom of the spring. After a few minutes have passed, the clay unsticks itself from the block and falls from rest to the ground. 1. What is the resulting period T of the block’s oscillation after the separation occurs? 2. As d approaches 0, what limit does T approach?A 2.5-kg block is held at rest against a spring (? = 1200 N/m), compressing it ? = 5.0 cm from its equilibrium position, then released. There is no friction except where indicated otherwise. A. Just to the right of point ?, the block traverses a rough section, (represented by the thick line between ? and ?), losing half of its kinetic energy to friction.
