A 0.2 kg object is whirled on the end of a string that is 0.5 m long at a speed of 8.3 m/s. Calculate the angular momentum of the object.
(Round your response to the nearest tenth, if necessary, and include the base unit abbreviation with your answer.)

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

i would think it's food chain
