Therefore,
This shows that is the solution to the differential equation
Answer:
The magnitude is 2093.4 lbs. The direction is 40N of W.
Step-by-step explanation:
To find the magnitude you have to do a^2 + b^2 = c^2 seeing as the two other sides would make the two legs of a right triangle.
To find the direction, you do tan^-1 (1350/1600) in order to find the degree.
This is an easy one!
Answer = 20.
