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=T-mg

a=(T-mg)/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)
