Because the penny absorbs the kinetic energy from the impact and releases it back into the environment as heat since the energy cannot be stored as potential energy.
We know, Weight = Mass * Gravity
Here, Mass = 20 Kg
Gravity = 10 m/s² [Approximate value ]
Substitute their values,
w = 20 * 10
w = 200 N
In short, Your Answer would be Option C
Hope this helps!
