The two balls are attached to the light rigid rod, which is suspended by a cord from the support above it. If the balls and rod, initially at rest, are struck with the force F = 19.1 lb, calculate the magnitudes of the corresponding acceleration ā of the mass center and the rate at which the angular velocity of the bar is changing.
