- A flywheel is rotating at 36.5 rev/s.What is the total angle, in radians, through which a point on the flywheel rotates in 29.7 s?A turntable is off and is not spinning. A 0.9 g ant is on the disc and is 14 cm away from the center. The turntable is turned on and 1.4 s later it has an angular speed of 33 rpm. Assume the angular acceleration is constant and determine the following quantities for the ant 0.7 s after the turntable has been turned on. Express all quantities using appropriate mks units. a => W = V= atan arad a= FnetThere 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 #
