A box,is resting on a smooth(frictionless)table.The mass of the box is 10 kg. (a)Determine the weight of the box and the normal force acting on(b)If the box is pushed down with a force of 40 Newton determine the normal force(c) If the box was pulled up with a force of 40 Newton,what now is the normal force on the box?


I know the question is long but I would greatly appreciate it if you solved it ..thank you!!!

    (a) The weight is M g = 98 N.
    (b) If you push down with 40 N force, add that to the weight
    (c) If you pull up with a 40N force, subtract that from the weight.

    Dear student,

    Oh lol don't worry about this being long i delt with more :)
    okay now lets understand that i cant give answers but my explanations...i might as well tell you the answer LO xD now Drwls said (a) The weight is M g = 98 N.
    (b) If you push down with 40 N force, add that to the weight
    (c) If you pull up with a 40N force, subtract that from the weight. Correct i would say that too BUT... theirs a ALOT SIMPLE WAY FAS (force,add,subb


    Eevee,

    p.s need more help?
