Final Kinetic Energy Calculator, Formula, Final Kinetic Calculation

Final Kinetic Energy Calculator:

Enter the values of Initial Kinetic Energy KEi_(J), Change dm_(kg) & Change in Velocity dV_(m/s) to determine the value of Final Kinetic Energy KEf_(J).

Final Kinetic Energy Calculator:

The Final Kinetic Energy Kfi_(J) in Joules is Equal to the Initial Kinetic Energy KEi_(J) in Joules is Addition of the Half into Multiply the Change in Mass dm_(kg) in kilogram and id Multiply the Change in Velocity dV_(m/s) in meter per second is squared.

The Equation of Final Kinetic Energy can be written as,

KEf_(J) = KEi_(J) + (½ * dm_(kg) * dV²_(m/s))

Here,

KEf_(J) = Final Kinetic Energy in Joules

KEi_(J) = Initial Kinetic Energy in Joules

dm_(kg) = Change in Mass in kilogram

dV_(m/s) = Change in Velocity in meter per second

Final Kinetic Energy Calculation:

1) Calculate the Final Kinetic Energy and given for the Initial Kinetic Energy = 450J, Change in Mass = 5kg, Change in Velocity = 7m/s.

Answer

KEf = KEi + (1/2 * dm * dV²)

KEf = 450 + (0.5 * 5 * 7²)

KEf = 572.5 Joules.

2) Calculate the Change in Velocity and given for the Initial Kinetic Energy = 450J, Change in Mass = 5kg, Final Kinetic Energy = 572.5 Joules.

Answer

KEf = KEi + (1/2 * dm * dV²)

572.5 = 450 + (0.5 * 5 * dV²)

dV = 7 m/s.
