A 4-centimeter rod is attached at one end A to a point on a wheel of radius 2 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 3.5 rev/sec. Thus, when t=1/21 sec, the rod is situated as in the diagram at the right below.
(a) How far is the right end of the rod (the point B) from the center of the wheel at time t=1/21 sec?
(b) Express the x-coordinate of the right end of the rod as a function of t:
(c) Express the speed of the right end of the rod as a function of t:
