an elevator weighing 500kg f moving upward and tension in the supporting cable is 50000N.find upward acceleration.

  • physics -

    tension=mg+ma
    solve for a

  • physics -

    As we know that
    T=(work done by gravitational force + Work done by upward pulling force)
    T=mg+ma
    ma=T-mg
    a=(T-mg)/m
    a={(50000 N) - (500 Kg x 9.8 m/sec2)}/500 kg
    a=90.2 m/sec2

  • physics -

    Sorry lil correct
    T=(work done by gravitational force + Net Force ma (not upward pulling force)
