Answer:
a = 1565217.39 ft / s ^ 2
t = 0.001725 seconds
Step-by-step explanation:
The first thing is to use the same system of units therefore we will pass the 28 inches to feet, like this:
28 in * (1 ft / 12 in) = 2.33 ft
Now yes, we can continue, we have the following data:
vi = 0
vf = 2700 ft / s
the equations in this case are as follows:
vf = vi + a * t
vf = a * t
rearranging for a
a = vf / t (1)
now with the position equation we know that:
x = vi * t + (a * t ^ 2) / 2
x = (a * t ^ 2) / 2 (2)
now replacing (1) in (2), we are left with:
x = (vf / t) * (t ^ 2) / 2
knowing that x would be 2.33 ft, which is when the cannonball exits the cannon.
2.33 = 2700 * t / 2
t = 2.33 * 2/2700 = 0.001725 seconds.
and now replace in (1)
a = vf / t = 2700 / 0.001725 = 1565217.39 ft / s ^ 2
Answer:
4.9%
Step-by-step explanation:
GDP is the growth domestic product of a country over a chosen time period
When the GDP growth rate is reported quarterly , you add together the four quarters for the year to find the annual GDP growth rate.
Given the four consecutive quarters as; 2% , 0.9%, 0.8% and 1.2%
Growth rate for the year will be;
4.9% is the annualized growth rate
Answer:
volume = lenght x width x height
v= 12x20x14
v=3,360 in³
D.) It is not correct because the second number tells you how far to go up or down, not across.
Second number represents y-coordinates, so they are the points in vertical direction, in that case you can't move in x-axis which is horizontal.
Hope this helps!
