Question

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

Answer 1

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

Answer 2

v = √(KE*2/m)

Step-by-step 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.
