An arrow is launched upward with a velocity of 192 feet per second from the top of a 95-foot stage. What is the maximum height a

Shalnov [3]

9514 1404 393

Answer:

671 feet

Step-by-step explanation:

There are a couple of ways to figure this. One is to use a sort of shortcut equation to find the distance traveled (d) by an object when subject to some initial velocity (v) and acceleration (a). Here the acceleration due to gravity is -32 ft/s².

v² = 2ad

d = v²/(2a) = (192 ft/s)^2/(2·32 ft/s²) = 576 ft

This height is in addition to the starting height of 95 ft, so the arrow's maximum height is ...

max height = 95 ft + 576 ft = 671 ft

__

Another way to work this problem is to start with the equation for ballistic motion. Filling in the given initial velocity and height, we have ...

h(t) = -16t^2 +192t +95

The time the arrow reaches the maximum height is the time representing the axis of symmetry of the parabola:

t = -(192)/(2(-16)) = 6

Then the maximum height is ...

h(6) = -16·6^2 +192·6 +95 = 671

The maximum height is 671 feet.

__

Additional comment

For the standard-form quadratic ...

y = ax^2 +bx +c

The axis of symmetry is ...

x = -b/(2a)

X^2 - 10x - 20 = 0, which number would have to be added to "complete the square"?

Airida [17]

Answer:

45

Step-by-step explanation:

When you're completing the square you're adding (b/2)^2 which in this case is (-5)^2 or 25. This is because when you rewrite it as a square binomial you write it in the form (x+(b/2))^2 which is going to result in x^2+b+(b/2)^2. Since you need to reach 25 you need to add 45 since the last value is at -20.
