A 50-kg person stands on a scale in a moving elevator while holding a 5-kg mass

suspended from a massless spring with the spring constant 1.08 kN/m. None of the

objects in the elevator is moving relative to the elevator, but the spring is stretched by

5cm. (a) Determine whether the elevator is accelerating, and if so, calculate the

acceleration vector. (b) What is the reading of the scale on which the person stands?
