The bone in the upper part of the cheek (the zygomatic bone) can be fractured by a 900-N force lasting 6.0 ms or longer. A hockey puck can easily provide such a force when hitting an unprotected face. (a) What change in velocity of an 0.11-kg hockey puck is needed to provide that impulsive force? (b) A padded face mask doubles the impact time. By how much does it change the force on the head behind the mask?
