In a closed system, as kinetic energy increases, what happens to potential energy?

<h2>Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.</h2>

What is the kinetic energy of a 50-kg child running to catch the school bus at

Vinvika [58]

Answer:

Option C

100 J

Explanation:

Kinetic energy, KE is given by

$KE=0.5mv^{2}$ where m is the mass and v is the velocity

Substituting 50 Kg for mass, m and 2 m/s for velocity v then we obtain

$KE=0.5*50*2^{2}=100 J$

Therefore, the child's kinetic energy is equivalent to 100 J
