The slider Pcan 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 0 = 0.83t - 0.046t, where e is in radians and t is in seconds. The slider is at r= 1.64 m whent 0 and thereafter is drawn inward at the constant rate of 0.13 m/s. Determine the velocity v and acceleration a of the slider when t 2.7 s. Express your answers in the x-y coordinate system. Answers: At t= 2.7s, v= (i -0.13 i) m/s 0.74 a-(i -0.43 i+ ) m/s? -0.26
