Question

Q1.    Beth, a construction worker attempts topull a stake out of the ground by pulling on a rope that isattached to the stake. The rope makes an angle of 60.20with the horizontal. If Beth exerts a force of 155.2N on the rope,what is the magnitude of theupward component of the force acting onthe stake?

Explanation / Answer

The upward force (x) is opposite the angle of 60.2 deg, sowe are talking about sine. sin 60.2 = x/ 155.2 x= 155.2 * sin (60.2) x = 134.677 Newtons
