    Both sentences are correct. You would choose to use "in" or "for' depending on what you mean to say. They have different meanings.

    I am able to do this homework for an hour. - I have to stop doing this homework after an hour has passed. It's too difficult, for example, or it gives me a headache. I need to stop after an hour, and then I can continue with it again later.

    I am able to do this homework in an hour. - I do not need more than an hour to finish this homework.

    I am able to do this homework in an hour. - I can finish this homework within the specified time frame of an hour. I don't need more than an hour. The time it takes me to finish this homework will not exceed one hour. ________________________________60 minutes|in an hour

    I am able to do this homework for an hour. - I can only dedicate an hour of time to this homework, and then I have to stop. This homework can only possess, use, or consume an hour of my time.

    This is my homework's hour.
    _____one hour____

    It can't have anymore time. I can only give it an hour.
