Answer:
768 N
Step-by-step explanation:
Apparent weight is the Normal force (N) acting on the student by the elevator floor.
N = mg + ma = (60 kg)(9.8 m/s2) + (60 kg)(3.0mm/s2) = 768 N
This is why you feel heavier when you are accelerating UP in an elevator. Try jumping in an elevator accelerating up. It's hard!
