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.
