- PROBLEM 2: A baseball catcher includes a 6-kg rod with a small net of negligible mass at point B. A spring of unstretched length 0.3 m is attached to the midpoint of bar AB at one end and to stationary point D at the other. A stopper at point E keeps the catcher in the vertical position before the pitch. Knowing the catcher just barely rotates when it catches a fastball of mass 0.18 kg, determine the required spring constant of the spring. Given = 1.5 m.
