if it was possible to triangulate all objects it would give the most accurate answer. So yes, it is the prefered method. However as this is not the case other methods are used, less accurate but more practical</span>
The equation for determining the kinetic energy of the system is,
KE = 0.5mv²
where m is the mass, v is velocity and KE is the kinetic energy. When both objects have the same mass, and velocity but different direction, they will have the same kinetic energy.
This is because the exponent in the velocity is squared cancelling out the effect of the sign appearing before the number.
