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?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
