Question

Forces of 15 kg and 10 kg act on a point with an angle of 60◦ between the forces. Find the magnitude of the
resultant force (to nearest tenth of a kilogram) and the angle (to the nearest degree) the resultant makes with the 15
kg force

Answer 1

Ann is trying to find the height of a building. She finds that the angle of elevation from the ground to the top of the
building is 38◦. She walks 150 feet straight back and finds the angle of elevation to the top of the building is 25◦.
Find the height to the nearest foot of the building

Answer 2

An airplane is headed northeast, bearing 45◦, with an air speed of 500 miles per hour, with a wind blowing with
bearing 315◦, at a speed of 75 miles per hour. Find the ground speed (to nearest tenth of a mph) and the actual
course of the plane (to nearest tenth of a degree).
