Answer:
a)
v=<400, 450+3t, 600-9.81t> m/s
r=<400t, 450t+3/2, 15+600t-9.81
/2> m/s
b) attach file
c) t=122.324s
d) z=18369.9854 m
Step-by-step explanation:
a)
The equation for velocity of each component is v=+at, in this case the x-axis component has acceleration 0
, the y-axis component has acceleration 3
and the z-axis component has -g
, where g=9.81
.
The equation for position of each component is x=+
t+a
/2,
with <,
,
>=<0,0,15>.
c) This time is t when z=0, with positive sign.
d)Solving the equation =
+ 2*a*(z-
) for z, with
=0.
Answer:
B. 18 bags
Step-by-step explanation:
First you need to determine the area of the vegetable garden. The vegetable garden is a rectangle with the following dimensions:
L = 24 ft
W = 9 ft
The Formula for the area of a rectangle is:
So let's solve it:
With that, we can figure out how many bags of fertilizer would be needed by dividing the area of the vegetable garden by how much one bag of fertilizer covers:
