2. 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: 8 = 0.8t t² 20 Where is is radians and t is in seconds The slider is at r= 1.6 m when t = 0 and thereafter is drawn inward at the constant rate of 0.2 m/s. When t = 4s, determine: a) The velocity vector and magnitude. b) The acceleration velocity and magnitude. c) The acceleration vector in cartesian unit vector format. S -X
