Answer: 351pi cubic feet</h3>
Work Shown:
r = 9 is the radius
h = 13 is the height
V = volume of cone
V = (1/3)*pi*r^2*h
V = (1/3)*pi*9^2*13
V = (1/3)*pi*81*13
V = (1/3)*81*13*pi
V = 351pi = exact volume in terms of pi
note: if you use pi = 3.14 as an approximation, then the cone has a volume of roughly 351*pi = 351*3.14 = 1102.14 cubic feet. Use a more accurate version of pi to get a more accurate approximation.

Answer:
367.64 meters
Step-by-step explanation:
Using the kinetic equation where:
<em>Vf ^ 2 - Vi ^ 2 = 2ax
</em>
We know that:
<em>Vf = 0 m / s
</em>
<em>Vi = 50 m / s
</em>
<em>
</em>
The acceleration can be calculated by means of F = M.a
F = -8500 (because it is stopping, braking force) and m = 2500 kg
We have left that a = F / M = -8500/2500 = -3.4 m / s ^ 2
Now reorganizing we have that:
<em>x = -Vi ^ 2 / 2a
</em>
<em>
</em>
replacing the values is:
<em>x = - (50 ^ 2) / (2 * -3.4)</em> = 367.64 meters and this would be the distance the car travels when it stops.
