your father pushed a 2-kg box across the floor with a net horizontal force of 10 n. what is the acceleration of the box

Step-by-step explanation:

The formula for force is:

If we rearrange the formula for acceleration (a) and divide both sides by m we get:

The net force is 10 Newtons. Let's convert the units to make the problem easier later on.

The mass is 2 kilograms.

Substitute the values into the formula.

Divide. Note the kilograms (kg) will cancel each other out (this is why we converted the units)

The acceleration of the box is 5 meters per second squared.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

answer: it is d
