A car with mass m traveling at speed v has kinetic energy k. what is the kinetic energy of a second car that has the same mass m
1 answer:
Kinetic energy, KE, is modeled by the formula 
, where m is the mass in kg and v is the velocity in m/s.
In this scenario, mass and one-half are constant but the velocity changes.
You can see that by squaring twice the velocity, that is equal to four times the original KE. Therefore, the answer is 4k.

Answer:
The time taken is
Explanation:
From the question we are told that
The length of steel the wire is
The length of the copper wire is
The diameter of the wire is
The tension is
The time taken by the transverse wave to travel the length of the two wire is mathematically represented as
Where is the time taken to transverse the steel wire which is mathematically represented as
here is the density of steel with a value
So
And
