A man in a lift holds a spring balance graduated to read in Newton, with a 1.29 kg mass hanging from it. Determine the readings of the spring balance when the lift: (a) moves upwards with a constant velocity (b) moves upwards with retardation of 3 m/s? (c) moves downwards with an acceleration of 0.5m/s?
