40kg
Explanation:
Given parameters:
Kinetic energy = 500J
Velocity = 5m/s
Unknown:
Mass of the object = ?
Solution:
Kinetic energy is the energy due to motion of a body. It is expressed as:
K.E = mv²
m is the mass of the body
v is the velocity
To find the mass, make it the subject of the expression:
m = }[/tex]
m = }[/tex] = 40kg

5320*14= 74480 gallons. <span>
First let us convert gallons to cm^3 and we get 2.819374858x10^8
cm^3.
We then multiply with density and then times 1000 to get it
in terms of tons.
Then multiply the number by 7 to get how many tons of crude
oil a single plane uses in 14 hrs.
Finally divide this by the production of crude oil.
