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- 0.90t - 0.041t², where e is in radians and t is in seconds. The slider is at r= 1.23 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 whent = 3.5 s. Express your answers in the x-y coordinate system. Answers: At t = 3.5 s, v = ( i i+ i j) m/s a = (i i+ i j) m/s2

Question
The slider P can be moved inward by means of the string S, while the slotted arm rotates about point . The angular position of the arm
is given by e = 0.90t - 0.041t², where e is in radians and t is in seconds. The slider is at r = 1.23 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 = 3.5 s. Express your answers
in the x-y coordinate system.
Answers: At t = 3.5 s,
v = (i
i+ i
j) m/s
a = ( i
i+ i
j) m/s2
