Mr Schecter, a baseball player in college, throws a "Large" size chicken egg, giving it as much kinetic energy as he can. Even with a throw at about 90 miles per hour (40 m/s) the kinetic energy is only 45 J. (An egg weighs only 5% of a kilogram.) A bed sheet is set up to stop this egg slowly by doing the same amount of work as the kinetic energy. The sheet is able to push with a force of 30. N. How far does the sheet have to stretch while it catches the egg?
