In a manufacturing process, a large, cylindrical roller is used to flatten material fed beneath it. The diameter of the roller is 7.00 m, and, while being driven into rotation around a fixed axis, its angular position is expressed as e-2.70²-0.250³ where @ is in radians and it is in seconds. (a) Find the maximum angular speed of the roller (b) What is the maximum tangential speed of a point on the rim of the roller? m/s (c) At what time I should the driving force be removed from the roller so that the roller does not reverse is direction of rotation? (d) Through how many rotations has the roller turned between 0 and the time found in part (c)? rotations
