Question
The slider P can be moved inward by means of the
string S as the bar OA rotates about the pivot 0.
The angular position of the bar is given by 0 = 0.4
+0.12t+ 0.06t³, where 0 is in radians and t is in
seconds. The position of the slider is given by r =
0.8 0.1t 0.05t2, where r is in meters and t is
in seconds. Determine and sketch the velocity and
acceleration of the slider at time t = 2 s. Find the
angles a and ß which v and a make with the posi-
tive x-axis.
