A 30.O-g ball at the end of a stung is swung in a vertical circle with a radius of 25.0 m. The rotational velocity Is 200.0 cm/s. Find the tension in the string: (a) at the top of the circle, (b) at the bottom of the circle, and (c) at a distance of 12.5 cm from the center of the circle (r=12.5cm).
Hungarian Adrian Annus won the gold medal for thehammer throw at the 2004 Olympics in Athens with a winningdistance of 83.19 meters.* The event consists of swinging a16-pound weight attached to a wire 190 centimeters long ina circle and then releasing it. Assuming his release is at a 45°angle to the ground, the hammer will travel a distance ofv02/gmeters, where g = 9.8 meters/second2and v0 is the linearspeed of the hammer when released. At what rate (rpm) washe swinging the hammer upon release?
Some dragonflies splash down ontothe surface of a lake to clean themselves. After this dunking, thedragonflies gain altitude, and then spin rapidly at about 1000 rpmto spray the water off their bodies. When the dragonflies do this“spin-dry,” they tuck themselves into a “ball” with a moment ofinertia of 2.6 * 10-7kg·m2. How much energy must the dragonflygenerate to spin itself at this rate?
One end of a cord is fixed and a small 0.550-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 1.50 m, as shown in the figure below. When ? = 17.0°, the speed of the object is 6.00 m/s. At this instant, find the magnitude of the tension in the string.

A puck of mass m=180g on a horizontal, frictionless table is connected to a string that passes through a small hole in the table, as shown in the following figure (attached) The puck is set into circular motion of radius R=50cm with a speed vi = 2.2 m/s. If the string is then pulled from the bottom as shown, so that the radius of the circular path is decreased to r=20cm, what is the final speed, vf, of the puck?
