Answer:
<u>D) The two angles are complementary</u>
Step-by-step explanation:
The formula for the vertical height, h, attained with a vertical take off speed of u is
u² - 2gh = 0
where
g = 9.8 m/s², acceleration due to gravity.
Because h = 1.29 m, therefore
u² = 2*9.8*1.39 = 27.244
u = 5.2196 m/s
Also, the time of flight, t, required when the vertical take-off speed is u is given by
ut - 0.5gt² = 0.
Therefore
5.2196t - 0.5*9.8*t² = 0
5.2196t - 4.9t² = 0
t(5.2196 - 4.9t) = 0
t = 0, or t = 5.2196/4.9 = 1.0652 s
t = 0 corresponds to take-off.
t = 1.0652 s corresponds to landing.
The hang time is 1.0652 s.
Answer:
Take-off speed = 5.22 m/s (nearest hundredth)
Hang time = 1.065 s (nearest thousandth)
Answer:
The answer is 17.80
Step-by-step explanation:
Just took the test hope this helps:)
The x component goes from 1 to 7 ( 6 to the right) and y component goes down 2 ( = -2) so the answer is the second choice. (6, -2)
Answer:
You technically can't do anything with it since it the algebraic expression doesn't factor.
