While placing a compact disc into a CD player, you notice a small chip on its edge. You attempt to play the CD anyway by lacing the CD into the player's deck with the chip at 0o = 12.6° as measured from the +x-axis. The CD begins to rotate with ngular acceleration a = 2.31 rad/s². If the CD has been spinning for t = 3.51 s and the disc has a radius of r = 6.00 cm, what are the x-y coordinates of the chip after this time, assuming the center of the disc is located at (0.00,0.00). X = y = cm cm

A “blink of an eye” is a time interval of about 150 ms for an average adult. The “closure” portion of the blink takes only about 55 ms. Let us model the closure of the upper eyelid as uniform angular acceleration through an angular displacement of 14.0°. What is the tangential acceleration of the edge of the eyelid while closing if the radius of the eyeball is 1.25 cm?

A discus thrower spins the discus in a circle of radius 80.0 cm. At a certain instant, the launcher is rotating at 10.0 rad/s and the angular speed is increasing at 50.0 rad/s^2. Find the magnitude of the acceleration at that instant. Hint: Calculate the tangential and centripetal components of acceleration of the puck at that instant.

There is a clever kitchen gadget for drying lettuce leaves after you wash them. It consists of a cylindrical container mounted so that it can be rotated about its axis by turning a hand crank. The outer wall of the cylinder is perforated with small holes. You put the wet leaves in the container and turn the crank to spin off the water. The radius of the container is 12.2 cm. When the cylinder is rotating at 2.45 revolutions per second, what is the magnitude of the centripetal acceleration at the outer wall? Number Units #
