3) A 10.0 kg object is hanging by a massless rope in an elevator that is traveling upward. The tension in the rope is measured to be 75.0 N. What are the magnitude and direction of the acceleration of the elevator?

Answer 1

tension=mg+ma
75=10(9.8+a) solve for a.
if a is positive, it is accelerating upwards, if negative, it is accelerating downward)
