Answer:
building footprint is 21000 sf
Explanation:
given data
floors = 8
total square footage = 168000 sf
to find out
building footprint
solution
we know building footprint is area where building built up same as perimeter of any building plan
so here
we have calculate here total perimeter
building footprint = ........1
put here value
here all floor are equal
building footprint =
building footprint = 21000 sf
so building footprint is 21000 sf
Answer:
V = 48.4m/s, θ = 73.6° below the horizontal.
Explanation:
Given h = 109.53m, x = range = 65m,
θ = 0°
This problem involves the concepts of projectile motion.
Let yo = h = 109.53m
y = final position on the y axis. = 0m (ground level)
y = yo + vosinθ – 1/2gt²
0 = 109.53 + vosin0° – 1/2×9.8×t²
0 = 109.53 – 4.9t²
4.9t² = 109.53
t² = 109.53/4.9 = 22.35
t = √22.35 = 4.73s
So it takes the ball t = 4.73 seconds to get to the ground from the launch point.
x = (vocosθ)×t
65 = (vocos0°)×4.73
65/4.73 = vo
Vo = 13.7m/s
Vx = Vox = Vocosθ = 13.7cos0° = 13.7m/s
Vy = Voy – gt = Vosinθ – gt
Vy = 13.7sin0° – 9.8×4.73 = –46.4m/s
V = √(Vy² + Vx²) = √(-46.4² + 13.7²)
V = 48.4m/s
θ = Tan-¹(vy/vx) = tan-¹(-46.4/13.7) = -73.6°
θ = 73.6° below the horizontal
V = 48.4m/s
gravity, fluid friction, and i think two more i just cant remember them
