Enter the total kinetic energy (J) and the velocity (m/s) into the Mass From Kinetic Energy Calculator. The calculator will evaluate and display the Mass.

## Mass From Kinetic Energy Formula

The following formula is used to calculate the Mass From Kinetic Energy.

M = 2*KE / v^2
• Where M is the Mass From Kinetic Energy (kg)
• KE is the total kinetic energy (J)
• v is the velocity (m/s)

To calculate the mass from kinetic energy, divide the kinetic energy by the velocity squared, then multiply by 2.

## How to Calculate Mass From Kinetic Energy?

The following example problems outline how to calculate Mass From Kinetic Energy.

Example Problem #1:

1. First, determine the total kinetic energy (J).
• The total kinetic energy (J) is given as: 2500.
2. Next, determine the velocity (m/s).
• The velocity (m/s) is provided as: 30.
3. Finally, calculate the Mass From Kinetic Energy using the equation above:

M = 2*KE / v^2

The values given above are inserted into the equation below and the solution is calculated:

M = 2*2500 / 30^2 = 5.55 (kg)

Example Problem #2:

For this problem, the variables needed are provided below:

total kinetic energy (J) = 6000

velocity (m/s) = 70

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

M = 2*KE / v^2 = ?
