3) what is the horizontal component of the velocity just before the ball strikes the ground?
4)how far from the base of the building did the ball strike the ground?
5) what is the speed of the ball just before it strikes the ground?

Answers

1) You need to solve t - $19.6=.5(9.8)t^2$
2) Then solve f $vf^2=2(9.8)(19.6)$
3) As it's constant it is still 10m/s
4) You need to use the time from part 1 times 10m/s
5) Use Pythagorean theorem with 10m/s and vf

Slope intercept form

Answers

Given:

The equation of the parallel line is

$y=-(5)/(2)x+7$

The required line passes through the point (-4,1).

To find:

The equation of line in slope slope intercept form.

Solution:

The slope intercept form of a linear function is

$y=mx+b$

Where m is slope and b is y-intercept.

On comparing the equation $y=-(5)/(2)x+7$ with slope intercept form, we get

$m=-(5)/(2)$

We know that the slopes of parallel lines are always same. So, the slope of the required line is $m=-(5)/(2)$ .

The line passes through the point (-4,1) with slope $m=-(5)/(2)$ . So, the equation of line is

$y-y_1=m(x-x_1)$

$y-(1)=-(5)/(2)(x-(-4))$

$y-1=-(5)/(2)(x+4)$

$y-1=-(5)/(2)x-10$

Adding 1 on both sides, we get

$y=-(5)/(2)x-10+1$

$y=-(5)/(2)x-9$

Therefore, the correct option is C.
