A 68 kg lady stands on a bathroom scale on elevator. Starting from rest, the elevator accelerates upward, getting its maximu  speed of 1.18 m/s in 0.900s. It travels with constant speed for the next 4.00s. Then, the elevator undergoes uniform acceleration in negative y direction for 2 s and comes to rest. What does the bathroom scale register 1) before the elevator starts to go up, 2) during the first 0.900s, 3) while it is traveling at constant speed, 4.) during the time its slowing down?
