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.
Alabama governor George Wallace stood in front of the entrance of the University of Alabama in an attempt to block the enrollment of two black students, Vivian Malone and James Hood. His infamous shout of "Segregation now! Segregation tomorrow! Segregation forever!" made people view him as one of the country's most destructive racist.
Answer:
I think it was a very close race, that's all i'm about to say before the government comes for me.
