Answer 1

Answer #1

Given that weight increases (740N to 830N) as soon as the elevator starts moving from rest.

So the elevator is accelerating and going upwards.

The scale will decrease if the elevator was going downwards.

Given weight, W 740N W 3D тg —

740N 740N т 9.81m/s2 g

m= 75.433kg

---------------------

Force on scale, F=mg+ma = 830N

F=740N 75.433kg* a 830N

74075.433* a 830

830 740 75.433
