Question

An arrow which has just been fired horizontally from a bow has been given mainly:

A) strain energy

B) sound energy

C) kinetic energy

D) thermal energy?

Choose only one answer.

Answer 1

kinetic energy

Answer 2

\[\large Kinetic \space Energy=\frac{1}{2}mass * velocity^2\]The arrow has mass already...and you added velocity to it (v) when you fired it. Therefore, you've increased its KE from 0 to some higher value.
