astraxan [27]
<span>Data:
mass =  110-g bullet
d = 0.636 m
Force = 13500 + 11000x - 25750x^2, newtons.

a) Work, W

W = ∫( F* )(dx) =∫[13500+ 11000x - 25750x^2] (dx) =

W =  13500x + 5500x^2 - 8583.33 x^3 ] from 0 to 0.636  =

W = 8602.6 joule

b) x= 1.02 m

W = 10383.5

c) %

[W in b / W in a] = 10383.5 / 8602.6 = 1.21 => W in b is 21% more than work in a.

In a nuclear power plant, nuclear reactions are used to heat steam, which turns a turbine. What energy conversion is happening i
mr_godi [17]
In a nuclear power plant, you start off with uranium (nuclear energy), and a lot of that nuclear energy is released by heat energy. Heat then boils water and drives a turbine for a generator, which creates kinetic energy, which produces electrical energy.

In other words, your answer is B.

What is the velocity of an upward moving 500kg elevator that has 4000 of energy
Mrrafil [7]

Answer:

4 m/s

Step-by-Step Explanation:

E = mgh and h = E/mg

So if you put your numbers in the formula : h = 4000J/500 * 10

you will get h = 4/5 meters

use this , If the elevator moves from top to the ground in a constasnt acceleration you will have all energy (4000 J) transformed into acceleration to speed up its motion.

(All potential energy will be turned into movement energy). As explained in this formula;

mgh = mv²/2 , solve out (v) from the equation

v = √2gh = √2·10·4/5 (digits are together- not related to the problem, just for clarification) = 4 m/s

Answer the velocity of the elevator is

4 m/s
