What is the average power of the horse?

[Moonbear]

instead of everybody complaining can we ask... qman do you understand how this is obtained?

And if s/he answers "yes?" Let the OP work through the problem themselves with hints and tips from the Homework Helpers, not outright answers. The purpose of this forum is not to make sure everyone has the right answers on their homeworks, but to make sure they've learned HOW they arrived at that answer and fully understand the subject so they can solve problems on their own. Handing an answer out doesn't accomplish that, neither does asking someone a yes/no question if they understand (some students do not realize they don't fully understand if they have an answer and can work backward since they haven't had a chance to work without that crutch). Let them SHOW you they understand by putting their own work into the problem.

Since there have now been TWO attempts from different people to give out an answer/complete solution here, this is an official notice from the staff letting folks know that we do NOT permit giving out complete answers.

Sorry to qman that your thread has been so disrupted.

If you didn't get a PM about that, look at Moonbear's post above or review the forum rules which can be found in the link below, which you agreed to when signing up.

Pay particular attention to the section labelled homework help.

Because you gave the answer to the problem. The guidelines state that we must try to help the OP by giving him hints and letting him solve the problem himself. Simply giving him the answer is not going to help and is not appreciated.


Now can we go back to helping the OP?

Do you understand what has been said about using only the horizontal component of the given force, because that is the only force doing work?

Good grief, folks, I've never seen such a mess in a homework thread before! If you can't help without giving out an answer, or you have something to say that is not directly related to helping the OP, STAY OUT OF THIS THREAD! Last warning! I'm getting an itchy trigger finger and am tempted to start giving out temporary bans for anyone who further disrupts the learning process here.

the only reason i thought it was kind of unfair to ridicule me was just because i posted my answer... all my teachers hand you the answers to the problems... they are in the back of the book a lot of times too... to get credit you have to show the work... all i provided was a number that he should arrive at if he understands the problem...

qman work it out and see what you get
