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. The top of the bottle has a diameter of  Dtop= 2 cm and the bottom of the bottle has a diameter of Dbot= 6.5 cm.The glass breaks when it is exposed to Pmax= 70 MPa of pressure.

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= 4.8 kg and moves downward at a speed of Vi= 5 m/s It collides elastically with the cork and rebounds with the same speed. The collision lasts for 1.2x10^-4 s. In this problem, the positive direction is upward.

What is the force that the fist exerts on the top of the bottle?

2 more parts coming! if u can get me the correct answer

Explanation / Answer

Given Rt=0.0100m, Rb=0.0325m, m=0.480kg, vi=-vf=5.00m/s, tc=120?s
