__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)} * dV^{2}_{(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

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 * dV^{2})

KEf = 450 + (0.5 * 5 * 7^{2})

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 * dV^{2})

572.5 = 450 + (0.5 * 5 * dV^{2})

dV = 7 m/s.
