Answer:

I found it would be quadrupled if it was doubled

Step-by-step explanation:

The kinetic energy of an object is the energy possessed by the object due to its motion. It is given by:

where

m is the mass of the object

v is its speed

From the equation, we notice that the kinetic energy is:

Directly proportional to the mass

Proportional to the square of the speed

In this problem, the initial kinetic energy of the object is

K = 100 J

Later, the speed of the object is doubled:

v' = 2v

Therefore, the new kinetic energy will be

So, we see that the kinetic energy will quadruple.
