Elevator Apparent Weight#
A 70.0 \(\rm{kg}\) person takes an elevator from the first floor to the third floor of the Arts building. The elevator accelerates (upward) at 7 \(\rm{m/s^2}\) for 1 \(\rm{s}\), maintains a constant velocity of 7\(\rm{m/s}\) for 1 \(\rm{s}\) and then slows to a rest in 1 \(\rm{s}\).
Part 1#
The person’s apparent weight is:
Answer Section#
686\(\rm{N}\) for all time intervals.
1176\(\rm{N}\) for the first second, 686\(\rm{N}\) for the second second, and 196\(\rm{N}\) for the third second.
696\(\rm{N}\) for the first second, 686\(\rm{N}\) for the second second, and 691\(\rm{N}\) for the third second.
686\(\rm{N}\) for the first second, 196\(\rm{N}\) for the second second, and 1176\(\rm{N}\) for the third second.
