Answer:
The correct option is (B) "100 J".
Explanation:
The formula of kinetic energy is given by :
[tex]E=\dfrac{1}{2}mv^2[/tex]
m is mass and v is velocity of object.
In this case, it is mentioned that a man on a high ladder releases a ball from rest which strikes the ground with 100 J of kinetic energy.
If he were to throw it straight upward instead, it will eventually reach the ground with a kinetic energy of 100 J. This is due to the conservation of energy.
