A35kg crate slides across floor which experts a 110n friction force on it. what horizontal force is required to move the crate at a steady speed across the floor.

The froce needed is 110 N

Explanation:

We need to make and sketch of the crate and the forces acting on it.

Since the movement is a constant velocity there is no acceleration, therefore, Newton's second law m*a = 0.

And from the equation deducted, we can appreciate that the opposite force to the friction force is the one that it's needed to move the crate at constant velocity.

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
