Question

What is the formula that can be used to find velocity if kinetic energy and mass are known?

Answer 1

Answer:

v = √(KE*2/m)

Explanation:

The formula to compute kinetic energy (KE) is:

KE = 1/2*m*v^2

where m refers to mass and v refers to velocity. Isolating v we get:

KE = 1/2*m*v^2

KE*2/m = v^2

v = √(KE*2/m)

Given kinetic energy and mass, then velocity can be computed.

Answer 2

The formula for kinetic energy is $\frac{1}{2}m\Delta v^2$. Thus, the equation for velocity is $v= \sqrt{ \frac{2TotalKineticEnergy}{m} }$.
