15. The figure shows a rotating wheel with radius 40 cm and a connecting rod AP with length 1.2 m. The pin P slides back and forth along the x-axis as the wheel rotates counterclockwise at a rate of 360 revolutions per minute. a. Find the angular velocity of the connecting rod, da/dt, in radians per second, when 0 = T/3.
