O centroid
Step-by-step explanation:
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has three medians, one from each vertex, and they all intersect each other at the triangle's centroid.
I hope this helps you
square root of 441
square root of 21.21
square root of 21^2
21
As you said it was dropped so in that case I'll take 78.4 meters as the height..
we know that
h = ut + 0.5*g*t(sqr)
t(sqr) = 78.4/(0.5*9.8) [g = 9.8 ms-2]
t = √16
t = 4
So it'd take 4 seconds
Answer:
Your competitor's roller coaster The maximum height of its heel is 80m. Horizontal distance between the starting point and the ending point is about 160m. ... 2) As parabola opens downward, vertex will be its maximum point. 3) Therefore, as the maximum height of its heel is 80m, y value of vertex will be 80.
