  • physical - ,

    Without the facts of problem 16, we have no way of knowing. Besides, how do we know the power was constant? It probably wasn't. Power increases with velocity, at constant thrust.

    The average power (in watts) was
    Pav = M*g*H/(120 seconds)

    H is the height attained (in meters) and M is the mass (in kg), which might have been changing.
