V= mph A typical break shot in pool (the opening shot) is about 20 mph with a ball that is about half the weight of the rock in the story. Considering this, what impact would a half-pound rock traveling at the calculated speed likely have on someone someone if it struck them in the forehead? O The impact would likely cause serious injury. The impact would hurt a little but would likely not cause any injury. Suppose David missed. What distance d would the rock travel before striking the ground if David released it from a height of H = 4.75 ft? Assume there is no air friction.
