Two workers are trying to move a heavy crate. One pushes on the crate with a force , which has a magnitude of 299 newtons (N) and is directed due west. The other pushes with a force , which has a magnitude of 308 N and is directed due north. What are (a) the magnitude and (b) direction of the resultant force + applied to the crate? Suppose that the second worker applies a force - instead of . What then are (c) the magnitude and (d) direction of the resultant force - applied to the crate? In both cases express the direction as a positive angle relative to due west.

a)![F=429.261\ N](/tpl/images/0519/0106/05738.png)
b)
with respect to the west direction.
c)![F=429.261\ N](/tpl/images/0519/0106/05738.png)
d)
with respect to the west direction.
Explanation:
Given:
force of push on the crate in the west direction,a)
The magnitude of resultant force:
b)
Now the direction of the force:
with respect to the west direction.
When the second worker will apply the same magnitude of force but negative then the direction of the force will be reversed.c) The magnitude of the resultant will remain the same.
d)
For the angle with respect to the west:
Now from the schematic:
