    Find force of gravity, normal force, and net force in Physics
    A crate of mass m (=10 kg) is placed at rest on a (frictionless) inclined plane, which has an angle (= 30 deg ) above horizontal

    1. The force of gravity on the crate is?
    2. The normal force on the crate is?
    3. The net force on the crate is?
    4. How long would it take the crate to slide 8 m down the incline?
    5. If the crate were kept from sliding by a rope pulling parallel to the incline, what would the size of the tension be

    Hi again, mikaelaq23!

    I've already answered you on another thread. Please don't continue to post homework questions on this site without showing what you think might be the answers first. If you do show what you think that answers might be and how you arrived at them, you'll be much more likely to have someone come along who can guide you in arriving at the correct answers and confirm for you if the answers that you have come up with are correct.

    Thanks!

    Do post what you did, right or wrong. We'll see where you got it wrong.

    Well I think all you guys are great.. I am studying auto electronics and we get quite a few science type questions... only problem is my tutor is a total :@%? And knows absolutely nothing...

    And yes unknown has bailed me out before...

    I just seek the help to help myself if you know what I mean...

    Any way... cheers
