5. A woman is whirling a 2.75 kg rock attached to a string around in a circle above her head. The rock moves in a horizontal circle with a radius of 16.3 cm with a speed of 3.75 m/s, while the tension force makes a slight angle above the horizontal as shown in the diagram. This arrangement is called a conical pendulum. The rock maintains a constant height of 1.95 m above the ground. The radial (r), tangential (t) and z-directions for circular motion are as indicated on the diagram. a) Determine the radial and z-components of the force of tension Side view Top view b) Determine the magnitude of the tension in the string and the angle that it makes with the horizontal c) The woman then lets go of the string and the rock flies off horizontally (meaning its initial vertical velocity is zero) and falls to the ground, tracing out a parabolic path as it moves through the air. How far horizontally from the woman's feet (Hint: you can do part c without answering parts a and ... and think about what kind of does the rock land?

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?
