Explanation / Answer

part a) upward acceleration a = 2.33 m/s^2

apparent weight = ma + mg = 72*2.33 + 72*9.8 = 873.36 N

part b) constant velocity => a = 0

apparent weight = mg = 72*9.8 = 705.6 N

part c) downward acceleration , a = 1.12 m/s^2

apparent weight = mg - ma = 72*9.8 - 72*1.12 = 624.96 N
