The kinetic energy will quadruple
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion. It is given by:
[tex]K=\frac{1}{2}mv^2[/tex]
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
[tex]K'=\frac{1}{2}m(v')^2=\frac{1}{2}m(2v)^2=4(\frac{1}{2}mv^2)=4K[/tex]
So, we see that the kinetic energy will quadruple.
