Triassic and Jurrasic are two of those periods
Answer:
My Take on this
The height of the wall can be related with the Horizontal distance traveled by the equation of the trajectory
y=xtan∆ - gx²(1+tan²∆)/(2u²)
The wall is at distance x1
So thats the horizontal distance we'll use... We need to find its corresponding vertical distance "y"
So
Applying the formula
∆=45°
x=x1
g=9.8ms-²
u=velocity of projection
Substituting
y= x1tan45 - 9.8x1²[1+(tan²45)]/2u²
tan45°=1
y= x1 -4.9x²(1 +1)/u
y= x1 - 4.9x²•2/u²
y= x1 - 9.8x²/u².
Native Americans in North America established themselves in 10 separate culture areas: the Arctic, the Subarctic, the Northeast, the Southeast, the Plains, the
Southwest, the Great Basin, California, the Northwest Coast and the
Plateau. They established themselves according to the type of landscape or terrain and weather they have.
So that they can establish a government and all form a
