There is a clever kitchen gadget for drying lettuce leaves after you was 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 ontainer is 11.4 cm. When the cylinder is rotating at 1.36 revolutions per second, what is the magnitude of the centripetal acceleration of the outer wall?

Step 1

Consider the radius of the container be *r*, the angular speed of the cylinder be *ω*, and tangen...
