In a home laundry dryer, a cylindrical tub containing wetclothes is rotated steadily about a horizontal axis, as shown inFigure P7.61. So that the clothes will dry uniformly, they aremade to tumble. The rate of rotation of the smooth-walled tubis chosen so that a small piece of cloth will lose contact withthe tub when the cloth is at an angle of θ = 68.0° above thehorizontal. If the radius of the tub is r = 0.330 m, what rate ofrevolution is needed in revolutions per second?

Greg Huegel, a Clemson All-American placekicker and former PHYS 2070 student, was nicknamed “The Grocery Store Kicker” by Dabo Swinney after being discovered as a walk on. When kicking a football, the kicker rotates his leg about the hip joint. As we proceed through this question, you will have to pull on information from past tests. If the velocity of the tip of the kicker’s shoe is 33.5 m/s and the hip joint is 1.25 m from the tip of the shoe, what is the shoe tip’s angular velocity in rad/s? The shoe is in contact with the initially nearly stationary 0.500 kg football for 20.0 ms. What average force is exerted on the football in Newtons to give it a velocity of 20.5 m/s? find the maximum range of the football in meters, neglecting air resistance.
