If we have 2 coordinates say: (x1,y1) and (x2,y2)
Then the formula for the midpoint is:
((x1+x2)/2,(y1+y2)/2)
And the formula for the distance is:
Sqrt((x2-x1)^2+(y2-y1)^2)
So here we have (-1,-4) and (-7,4)
The midpoint is:
((-1+-7)/2,(-4+4)/2) = (-8/2,0/2) = (-4,0)
The distance is:
Sqrt((-7- -1)^2+(4- -4)^2)
= sqrt((-6^2)+(8^2))
=sqrt(36+64)
=sqrt(100)
=10
The answer will be letter "B" you take 450 times it by 4.29
and u get 1,930.50
Answer:
15.3 m/s
Step-by-step explanation:1) Find the gravitational potential energy using the equation :


2) Then use the equation for kinetic energy to solve for the velocity:


C.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 77, -77
