Question

which site represents the maximum kinetic energy?
options: a, b, c

Explanation:

Kinetic energy (KE) depends on mass and speed, given by $KE=\frac{1}{2}mv^2$. For the same hammer (constant mass), KE is highest at maximum speed. Position C shows the hammer just before striking the nail, where it has accelerated fully from its raised position, reaching its highest speed.

Answer:

C. The hammer at position C (just before impact with the nail)
