Answer:
W = 1.545E6 J total work
P = W / t = 1.545E6 J / 3 sec = 5.15E5 J/sec = 515,000 J/sec (Watts)
Using definition of power
When we're working problems that involve a pendulum, we almost always IGNORE anything else besides gravity.
Anything else besides gravity that could influence the motion of a pendulum is something that we would eliminate if we could.

This question is probably fishing for the answer "<em>friction</em>".
because of gravitional pull
