A gadget to dry lettuce leaves consists of a small perforated cylinder container mounted inside a larger cylinder container so that the small cylinder can be rotated about its axis by turning a hand crank. Wet leaves are placed in the small cylinder and spun to remove
water. If the radius of the small cylinder is 15.0 cm and rotates at 3.0 revolutions per second, determine the magnitude of the
centripetal acceleration at the outer wall of the small cylinder in m/s2. Provide an answer to one decimal place, do not include units.
