The force exerted by expanding gases is what propels a shell out of a gun barrel. Suppose a force that has an average magnitude F propels the shell so that it has a speed v at the instant it reaches the end of the barrel.
A) What magnitude force is required to double the speed of the shell in the same gun?

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0Β° north of east. the plane then flies to town b, located d2 = 230 km at 30.0Β° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)
