Homework Statement
I have this packet and one of the questions state:
The constant force F with components Fx=3N and Fy=4N act on a body while that body moves from the point P (x=2 m, y=6 m) to the point Q (x=14 m, y=1 m). How much does the force do on the body during this process?
the options are as follows:
a. 16 J
b. 30 J
c. 46 J
d. 56 J
e. 65 J
Homework Equations
I have the equations to find energy:
kinetic: K=(1/2)mv^2
gravitational: mgh
The Attempt at a Solution
but I'm not sure if I'm missing something. So far I have figured out you need to keep the x and y components separated and calculate each but I think I'm doing something wrong. I've gotten to Work = Force * cos(t) * change in distance but I'm just confusing myself. Help?
Also, I am taking the Physics: C Mechanics exam, what are some topics and questions that would help me prepare for it?
