There will be another question later building on this one. Be sure to save your computations for referencing later. A 8-centimeter rod is attached at one end to a point A rotating counterclockwise on a wheel of radius 4 cm. The other end B is free to move back and forth along a horizontal bar that goes through the center of the wheel. At time t=0 the rod is situated as in the diagram at the left below. The wheel rotates counterclockwise at 1.5 revolutions per second. Thus, when t=1/9 sec, the rod is situated as in the diagram at the right below. Note that the wheel has its center at the origin. A A B 'h' B ' '7 ' (a) When t=1/9 sec, Point A has coordinates ( , ) and point B has coordinates ( ,0). (b) The angular ve ocity for the circular motion of the point A is cu: radians per second (c) Express the x and y coordinates of point A as a function of t: X= and y: (d) Express the x-coordinate of the right end of the rod at point B as a function of t: (e) Express the velocity of the right end of the rod as a function of t: centimeters per second
