VIII. Questions and Problems: Concurrent Forces
1.
A woman walks eastward for 5 km and then northward for 10 km. How far is she
from her starting point? If she had walked directly to her destination, in what
direction would she have headed?
2. A woman in a car on a level road sees an airplane traveling in the same direction
that is climbing at an angle of 30° above the horizontal. By driving at 110 km/h
she is able to stay directly below the airplane. Find the airplane's velocity.
3. Using the component method, find the magnitude and direction of the resultant of
a 5-N force that acts at an angle of 37° clockwise from the +X axis, a 3-N force
that acts at an angle of 180° clockwise from the +x axis, and a 7-N force that acts
at an angle of 225° clockwise from the +X axis. Compare your answer using the
Polygon method. Use scale: 1cm = 2N
