Answer:
Correct answer: Ek = I² / 2 · m
Explanation:
The formula by which kinetic energy is calculated is:
Ek = m V² / 2
The formula by which momentum i prefer the name impulse is calculated is:
I = m V
We will transform the formula for kinetic energy on the next way:
Ek = m V² / 2 we will multiply numerator and denominator with m and get:
Ek = m² V² / 2 m = (m v)² / 2 m = I² / 2 m
Ek = I² / 2 m
