Two objects, a and b, are connected by hinges to a rigid rod that has a length l. the objects slide along perpendicular guide rails as shown in the figure below. assume object a slides to the left with a constant speed v.
(a) find the velocity vb of object b as a function of the angle θ. (use any variable or symbol stated above as necessary.)
vb =
(b) describe vb relative to v. is vb always smaller than v, larger than v, or the same as v, or does it have some other relationship?
