The work done on a system is time dependent, where W(t) = (2.00
J/s)t + (0.500 J/s3)t3. (a) What is the instantaneous power at t =
0.665s and (b) t = 1.16s? Now let us assume that we know the
instantaneous power to be P(t) = (3.50 J/s2)t + (1.50 J/s3)t2.
Assuming that there is no work done on the system at t = 0, what is
work done at (c) t = 0.865s and (d) t = 1.25s?
