a crate is pushed to the top of a frictionless inclined plane 15 m long with a force of 25 N.

If the crate weighs 125 N, how high is the inclined plane?

0.5 m
1 m
3 m
or
5 m

  • physics -

    mgh=25*15
    h= 25*15/125
    h= 3m

  • physics -

    W=F(cosx)d=mgh(potential energy)
    25(cos0)(15)=375
    mgh=(12.77)(9.8)h
    375=125h
    375/125=h
    h=3
