A glass soda bottle is emptied of soda and filled to the very top with water. A cork is carefully fitted into the top of the bottle, leaving no air between the cork and the water. (Figure 1) The top of the bottle has a diameter of DtopDtopD_top = 2.00 cmcm and the bottom of the bottle has a diameter of DbotDbotD_bot = 6.50 cmcm . A student hits the cork sharply with her fist and the bottom of the bottle breaks. The student's fist has a mass of mmm = 0.480 kgkg and moves downward at a speed of viviv_i = 5.00 m/sm/s . It collides elastically with the cork and rebounds with the same speed. The collision lasts for ttt = 1.20×10−4 ss . In this problem, the positive direction is upward. What is the force that her fist exerts on the top of the bottle?
