    A forklift raises a crate weighing 8.35 × 10Æ newtons to a height of 6.0 meters. What amount of work does the forklift do?

    I will try and set up an equation. However, I am no Physics wiz, so it may take a while. @ilovemybabies Please refrain from using vulgar language. It's against the CoC, whether you are swearing or typing vulgar words in such a way that it bypasses the Language filter.

    @ilovemybabies Please don't use abusive language here. I know that you need help here. But you gotta be polite and nice to others. Thanks :) I'd instruct you to close this question, and start a new post asking for help

    I'm working it out to make sure I'm correct before attempting to help. However, are there options for this? If so, can you list them?

    Well, alrighty then. I'll come back if he/she decides to post again (as ash said) politely, and if he/she wants to participate in it rather than slapping down a question and sayin' "helpppp."

    If the object has 9.8J of KE when it hits the ground, it must have had 9.8J of PE when it was released (conservation of energy, it's the law) Because PE = mgh, and you know PE, g, and h, solve for m.
