The slider Pcan be moved inward by means of the string 5, while the slotted arm rotates about point O. The angular position of the arm s given by 0 = 0.68t - 0.045t?, where e is in radians and t is in seconds. The slider is at r= 1.40 m when t = 0 and thereafter is drawn nward at the constant rate of 0.10 m/s. Determine the velocity v and acceleration a of the slider when t = 2.2 s. Express your answers n the x-y coordinate system.

The slider P can be moved inward by means of the string S, while the slotted arm rotates about point O. The angular position of the arm is given by e = 0.68t - 0.045t?, where e is in radians and tis in seconds. The slider is at r = 1.40 m when t = 0 and thereafter is drawn inward at the constant rate of 0.10 m/s. Determine the velocity v and acceleration a of the slider when t = 2.2 s. Express your answers in the x-y coordinate system. Answers: At t = 2.2 s, v = ( i i+ i j) m/s a = ( i i j) m/s2
