How to Calculate Speed Based on Kinetic Energy

What is the formula to calculate speed based on kinetic energy?

Given a kinetic energy of 82J and a mass of 80 kg, how can we determine the speed of the object?

Formula to Calculate Speed Based on Kinetic Energy

To calculate the speed based on kinetic energy, we can use the formula:

v = √(2 * ke / m)

When calculating the speed of an object based on its kinetic energy and mass, we need to use the formula v = √(2 * ke / m), where v represents the speed, ke is the kinetic energy, and m is the mass of the object.

In this case, the given kinetic energy is 82J and the mass is 80 kg.

Substitute the values into the formula:

v = √(2 * 82 / 80) = √(164 / 80) = √2.05 ≈ 1.43 m/s

Therefore, the speed of the object would be approximately 1.43 meters per second when given a kinetic energy of 82J and a mass of 80 kg.
