Question:
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 ?The top of the bottle has a diameter of Dtop? ?cm?and the bottom of the bottle has a diameter of Dbot? ?cm?
A student hits the cork sharply with her fist and the bottom of the bottle breaks. The student's fist has a mass of m ?kg ?and moves downward at a speed of vi? ?ms? ?It collides elastically with the cork and rebounds at the same speed. The collision lasts for t?times ?s? ?In this problem, the positive direction is upward.
Figure ?of There is a glass bottle with a cork and a scheme of it on the xyplane. The glass bottle is filled with water to the cork and is oriented along the y axis. The scheme shows the diameters of the top and the bottom of the bottle. They are ?and ?centimeters respectively.
Part A What is the force that her fist exerts on the top of the bottle? Express your answer in newtons to three significant figures.
