A plane is flying with an airspeed of 140 miles per hour and heading of 155∘degrees. The wind currents are running at 40 miles per hour at 175∘degrees clockwise from due north. Use vectors to find the true course and ground speed of the plane. Round to the nearest whole number.  true course - ground speed -

Find the angle theta between the given vectors to the nearest tenth of a degree. You must show work on a separate sheet of paper to rebeive credit. U=12i+7j V=-4i+5j

Use the component method to add the vectors A and B shown in the figure. The length of B is 2.55 m and the angle e = 25.0°. Express the resultant A + B in unit-vector notation. A + B = 3.00 m

Solve applications involving vectors. An airplane is flying on a compass heading (bearing) of 330° at 345 mph. A wind is blowing with the bearing 310° at 50 mph. (a) Find the component form of the velocity of the airplane. (b) Find the actual ground speed and direction of the plane.
