Problem: A child with a mass of 30 kg is standing on a spring scale in an elevator.
Part A: If the spring scale reads 360 N, what are the magnitude and direction of the acceleration of the elevator at this time? The acceleration due to gravity is 10 m/s2.
I need help to determine the magnitude and direction of the acceleration of the elevator at this time.
