How do I find the velocity when I already have kinetic energy (power) and mass?
I know the equation for Kinetic energy is:
(mass X velocity,squared)
_____________________
2
(mv, squared) /2
but I already have the kinetic energy (power) and the mass. How do I rearrange the equation so I can find velocity?
KE = 0.5mv^2
2KE = mv^2
2KE / m = v^2
v = sqrt(2KE / m)
In the formula for kinetic energy, it's is only the velocity that is squared, not the mass as well.
Kinetic energy is just that, energy, NOT power. Power is a measure of energy per unit time. Energy is measured in joules (J), power is measured in watts (W = J/s).
