Question

A.)Use your knowledge of bearing, heading, and true course to sketch a diagram that will help you solve the problem.

A.) plane is flying with an airspeed of 190 miles per hour and heading 150°. The wind currents are running at 40 miles per hour at 170° clockwise from due north. Use vectors to find the true course and ground speed of the plane. (Round your answers to the nearest ten for the speed and to the nearest whole number for the angle.)
______ mi/hr with heading ____°

B.)A heavy log is dragged across the ground by two horses pulling on ropes (see the figure below). The magnitudes of the tension forces in the direction of the ropes are 52 pounds and 78 pounds. If the angle between the ropes is 26°, find the magnitude of the resultant force. (Round your answer to the nearest whole number.)
______ lb

C.)The following problem refers to the figure below, which is a diagram of a bike frame. The frame can be approximated as two triangles that have the seat tube as a common side.

Suppose the frame has a top tube length of 53.5 centimeters, a seat tube length of 48.0 centimeters, and a seat angle of 75.0°. Find the length of the down tube and the angle between the seat tube and the down tube. (Round your answers to one decimal place.)

Explanation / Answer

(a) 170 mi per hour with heading 60 degrees.

(b) 200 pounds.

(c) Length of the down tube is 6 cm.

Angle between seat tube and down tube is 45 degrees.
