It is a clever kitchen washing out to dry lettuce leaves after you. It consists of a cylindrical tank mounted so that they are rotated on its axis by turning a crank. The outer wall of the cylinder is perforated with small holes. They represent the wet leaves in the container and turn to turn the crank to the water. The radius of the container is 12 cm. When the cylinder is turned to 1. 9 revolutions per second, which is the amount of centripetal acceleration on the outside?

Centripetal acceleration = v^2 /r or rω^2 or 4π^2 N^2 r.
Where v is the speed, ω is the angular speed, N is the revolutions/s and
r is the radius.
Aceleration = 4π^2 N^2 r. = 4π^2* 1.9^2 *0.12 = 17.10 m/s^2
