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