The screw eye is subjected to the two forces shown. Express each force in Cartesian vector form and then determine the resultant force. Find the magnitude and coordinate direction angles of the resultant force.
The route followed by a hiker consists of three displacement
vectors , , and . Vector is along a measured trail and is 1360 m in
a direction 16.0 ° north of east. Vector is not along a measured
trail, but the hiker uses a compass and knows that the direction is
27.0 ° east of south. Similarly, the direction of vector is 15.0 °
north of west. The hiker ends up back where she started, so the
resultant displacement...

The route followed by a hiker consists of three displacement
vectors , , and .
Vector is along a measured trail and is 2670 m in a
direction 27.0 ° north of east. Vector is not along a
measured trail, but the hiker uses a compass and knows that the
direction is 34.0 ° east of south. Similarly, the direction of
vector is 42.0 ° north of west. The hiker ends up back
where she started, so the resultant displacement is zero,
or + + = 0. Find the...
