A football is kicked vertically upward from a height of 2 feet with an initial speed of 50 feet per second. The formula h=2+50t-

Oksanka [162]

Answer: 38 feet.

Step-by-step explanation:

The equation of motion of a body thrown vertically upwards:

$\displaystyle\\\boxed {h=h_0+v_0t-\frac{gt^2}{2} \ \ \ \ \ (1)}$ ,

$h_0=2 \ feet\ \ \ \ v_0=50\ feet\ per\ second.$

Substitute in formula (1) the value t=2 c:

$h=2+50*2-16*2^2\\h=2+100-16*2*2\\h=102-64\\h=38\ feet.$

Find the solution of this system of equations.

Vilka [71]

The answer is (2,0)

Explanation

So I’m gonna use substitution to help me solve this problem. I’m gonna solve for x.

X-y=2

+y. +y

X= y + 2

Now that we have solved for x we are going to plug it into the first equation!
Shown like this

Y+2 - 10y = 2

Then we solve it as a normal problem

So first we combine light terms

-9y+2=2

Then we isolate the variable

-9y+2=2
-2. -2

-9y = 0

Then we divide by -9 on both sides

-9y /-9 = 0 / -9
Y = 0

Now that we solved for y we plug it into one the equations to get the x value!

X - 0 = 2
X=2

The solution is (2,0)
