Kinetic energy
Pushing is energy in motion and energy in motion is classified as (KE) kinetic energy
KE = 0 (because velocity is 0)
PE = mgh = 2kg*9.8m/s^2*40m= 784 joule
<u>Explanation:</u>
KE stands for kinetic energy. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Since in this case, the building is still and therefore it does not have any kind of kinetic energy because there is not acceleration.
Answer:
4.8
Step-by-step explanation:
Um, I'm not sure how to explain, but watch a khan academy video on it
Answer:
Step-by-step explanation:
We can use the FOIL method to expand two multiplied binomials. It states that 
. The FOIL method stands for First(first terms) outer(outer terms) inner(inner terms) last(last terms).
So, we can expand our binomials now!
The equation that represents profit is $40x - $20.
The profit after 5 days in business is $180.
The profit after 10 days in business is $380.
The profit after 10 days in business if revenue is $45 is $430.
<h3>What is profit? </h3>
Profit is total revenue less total cost.
Profit = total revenue - total cost
Profit = $40x - $20
Where:
x = number of days
<h3>What is the total profit after 5 days and 10 days? </h3>
$40(5) - $20
= $200 - $20
= $180
$40(10) - $20
$400 - $20
$380
<h3>What is total profit if revenue is $45? </h3>
$45(10) - $20
= $450 - $20
= $430
