A crate is sliding on the floor. If there is a total force acting on the crate in the same direction as it is sliding, the crate would A) slow down
B) speed up
C) remains the same speed
​​​​​​​ D) slow down, change direction and then speed up going the other way,
E) remains the same speed but changes direction

But we do not know whether the force is pushing or pulling (the same direction (both forces are parallel) but: [ ]<-F-- or [ ]--F-->). I suppose the correct answer is B

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

wavelength divides in half and speed stays the same.
