Homework Statement
A metal bar of length l in the figure below has one end attached at a point P to a circle ofradius a < l. Point Q at the other end can slide back and forth along the x–axis.
(a) Find x as a function of θ (θ=angle POQ).
(b) Assume the lengths are in centimeters and the angular speed,dθ/dt, is 2 radians persecond counter clockwise. Find the speed at which point Q is moving when θ =π/2 and when θ =π/4. Give units.
