1. The problem statement, all variables and given/known data 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. 2. Relevant equations 3. The attempt at a solution Having a hard time understanding what to do for this problem.
