2/144 The slider P can be moved inward by means of the string S, while the slotted arm rotates about point 0. The angular position of the arm is given by A = 0.81 - where 0 is in radians and t is in sec- 20' onds. The slider is at r = 1.6 m when I = 0 and thereafter is drawn inward at the constant rate of 0.2 m/s. Determine the magnitude and direction (expressed by the angle « relative to the x-axis) of the velocity and acceleration of the slider when t = 4 s. S Problem 2/144
