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

tension=mg+ma
solve for a 
As we know that
T=(work done by gravitational force + Work done by upward pulling force)
T=mg+ma
ma=Tmg
a=(Tmg)/m
a={(50000 N)  (500 Kg x 9.8 m/sec2)}/500 kg
a=90.2 m/sec2 
Sorry lil correct
T=(work done by gravitational force + Net Force ma (not upward pulling force)
