Suppose that a wind is blowing in the direction s45°e at a speed of 30 km/h. a pilot is steering a plane in the direction n60°e at an airspeed (speed in still air) of 100 km/h. the true course, or track, of the plane is the direction of the resultant of the velocity vectors of the plane and the wind. the ground speed of the plane is the magnitude of the resultant. find the true course and the ground speed of the plane.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
