Physics Q
by Ahmed Sun May 30, 2010 1:02 pm
Beth, a construction worker, attempts to pull
a stake out of the ground by pulling on a rope
that is attached to the stake. The rope makes
an angle of 51.1◦ with the horizontal.
If Beth exerts a force of 118.1 N on the
rope, what is the magnitude of the upward
component of the force acting on the stake?
Answer in units of N.
