Problem 1R

As seen from above, a stubborn stump is pulled by a pair of ropes, each with a force of 200 N, but at different angles as shown. From greatest to least, rank the net force on the stump.

Step-by-Step Solution:

Solution Step 1 of 2 Force is a vector, so it has both magnitude and direction. In order to calculate the resultant net force, when two vectors are acting on an object at certain angles between them; we have to use parallelogram law of vectors. That is,if two forces are acting simultaneously on a object are represented in direction and magnitude by using two adjacent sides of the parallelogram, while the resultant force can be represented in direction and magnitude as the the diagonal of the parallelogram. As two applied forces are equal, The resultant net force vector is given by, R = + F + 2FFcos Where R is the resultant net force, F is the applied force, is the angle between the two applied force.
