Two workers are trying to move a heavy crate. One pushes on the crate with a force A. which has a magnitude of 563 newtons (N) and is directed due west. The other pushes with a force 3. which has a magnitude of 318 N and is directed due north. What are (a) the magnitude and (b) direction of the resultant force A + B applied to the crate? Suppose that the second worker applies a force-B instead of B. VWhat then are (c) the magnitude and (d) direction of the resultant force A-3 applied to the crate? In both cases express the direction as a positive angle relative to due west.

A pack of four Arctic wolves are exerting four different forces upon the carcass of a 500 kg deadpolar bear. Wolf one is pulling on the bear with a force of 20 Newtons (N) due north. Wolf twois pulling on the bear with a force of 30 N, 30 degrees north of west. Wolf three is pulling onthe bear with a force of 25 N due west, and wolf four is pulling on the bear with a force of 35 N,10 degrees west of south. Determine the net force acting upon the polar bear and the directionof that force measured north of west. Then compute the magnitude of the acceleration of thepolar bear.

This much information can be scary at first but we are just going to use the techniqueswe have learned above and work our way through. Take a deep breath. You will be fine.Your first step should always be to draw a diagram of the situation. Do so here: (Hint: Drawthis as though you are looking down on it from directly above with the bear at the origin ofyour coordinate system, like a two-dimensional tug-o’-war…
