A 60.0kg teacher (including the parachute) is skydiving! As the parachute opens, the system experiences a 1600N drag. What is the magnitude of the net force on the system?

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
