SUMMARY
The discussion centers on calculating instantaneous power delivered to a body of mass m, accelerated uniformly from rest to speed v in time T. The correct formula for power as a function of time is derived as P(t) = m(Vf/T)^2t, where Vf is the final velocity. The initial attempt incorrectly used P = [0.5m(v/T)^2] / t, leading to confusion regarding unit consistency. The key takeaway is the application of the formula P = Fv, which simplifies the calculation of power in this context.
