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 43-lb roller and the floor is ls = 0.12, 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.
