Initial Momentum Calculator:
Enter the values of Final Velocity Vf(m/s), Change in Velocity dV(m/s) & Mass m(kg) to determine the value of Initial Momentum pi(kg*m/s).
Initial Momentum Formula:
The Initial Momentum pi(kg*m/s) in kilogram meter per second is equal to the Final Velocity Vf(m/s) in meter per second is subtracted by the Change in Velocity dV(m/s) in meter per second and then multiply the Mass m(kg) in kilogram.
The Formula of Initial Momentum can be writtern as,
pi(kg*m/s) = ( Vf(m/s) – dV(m/s) ) * m(kg)
Here,
pi(kg*m/s) = Initial Momentum in kilogram meter per second
Vf(m/s) = Final Velocity in meter per second
dV(m/s) = Change in Velocity in meter per second
m(kg) = Mass in kilogram
Initial Momentum Calculation :
1)Calculate the Initial Momentum and given for Final Velocity = 80m/s ,Change in Velocity = 70m/s , Mass = 11kg.
Answer
pi = ( Vf – dV ) * m
pi = ( 80 – 70 ) * 11
pi = 110kg*m/s.
2)Calculate the Mass and given for Final Velocity = 80m/s ,Change in Velocity = 70m/s , Initial Momentum = 110kg*m/s.
Answer
pi = ( Vf – dV ) * m
110 = ( 80 – 70 ) * m
m = 11kg.
