You need to pick up a book off the floor and place it on a tabletop. You do 1.56J of work to lift the book with a force of 300N. What is the distance?

Work done = Froce × distance

Now, keeping this formula in mimd, we can find the distance as follows;

= 1.56 = 300 × distance

= 1.56/300 = distance

= 156/30000 = distance

= 0.0052 m = distance

Lets convert it into cm so that you don't get troubled seeing it :)

= 1 m = 100cm

= 0.0052 × 100

= 0.52 cm

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

are there options? cause you ain’t. real specific
