# Elevator Apparent Weight#

A 80.0 $$\rm{kg}$$ person takes an elevator from the first floor to the third floor of the Arts building. The elevator accelerates (upward) at 8 $$\rm{m/s^2}$$ for 1 $$\rm{s}$$, maintains a constant velocity of 8$$\rm{m/s}$$ for 1 $$\rm{s}$$ and then slows to a rest in 1 $$\rm{s}$$.

## Part 1#

The person’s apparent weight is:

• 784$$\rm{N}$$ for all time intervals.
• 1424$$\rm{N}$$ for the first second, 784$$\rm{N}$$ for the second second, and 144$$\rm{N}$$ for the third second.
• 794$$\rm{N}$$ for the first second, 784$$\rm{N}$$ for the second second, and 789$$\rm{N}$$ for the third second.
• 784$$\rm{N}$$ for the first second, 144$$\rm{N}$$ for the second second, and 1424$$\rm{N}$$ for the third second.
