I am trying to work out power from acceleration and mass alone. But i'm having a mind blank with regard to the actual calculation and it is driving me crazy.(adsbygoogle = window.adsbygoogle || []).push({});

Force = Mass x Acceleration

Work = Mass x Acceleration x Distance

Power = Work / Time

Power = Mass x Acceleration x Velocity

Hence: Power = Mass x Acceleration x Integration of Acceleration

So from this what should the Power be for the following situation?

Mass = 5 Kg

Acceleration at t = 0 sec is 4.2 ms^-2

Acceleration at t = 0.2 sec is 8.4 ms^-2

Does a point need to be interpolated on the line to work the acceleration

and integration of acceleration before it can be placed into the equation?

Plus as the time between the two values is 0.2 sec does the answer need to be multiplied by 5?

Thanks
