An object is thrown horizontally from the open
window of a building. If the initial speed of the
object is 20 m/s and it hits the ground 2.0 s later,
from what height was it thrown? (Neglect air
resistance and assume the ground is level.)
Initial vertical velocity = 0
formula: s = ut + (1/2)*g*t^2
s = 0 + 1/2*9.8*2^2
s = 9.8*2 = 19.6 m
<h2>Arch Carries the thrust of Weight - Option D</h2>
An arch carries the thrust of weight to its sides. With a post-and-lintel, the horizontal part of the structure supports all the weight above it. The reason is that the post and lintel is a system of construction. In this the powerful parallel components are kept up by powerful upward components that has large cavities between them.
Therefore, an arch carries the thrust of weight to its sides for balancing purposes.
the answer is 5 m up AKA "B"

Answer:
denisity = 52.33 g/c
Explanation:
Density:
We have that m = 785 and that v = 15 c.
d = 52.33
