The man pushes on the roller with force P through a handle that connects to the central axle of the roller. If the coefficient of static friction between the 69-lb roller and the floor is g = 0.11, and the force Pis maximum so that the roller is about to slip, determine the angular acceleration of the roller (in rad/s2). Assume the roller to be a uniform cylinder. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take g = 32.2 ft/s². P Your Answer: Answer 30° 1.5 ft S
