A 75.0 kg man stands on a platform scale in an elevator. Starting from rest, the elevator
ascends, attaining its maximum speed of 1.20 m/s in 1.00 s. It travels with this constant speed for
the next 10.00 s. The elevator then undergoes a uniform acceleration in the negative y direction
for 1.70 s and comes to rest. What does the scale register:
(a) before the elevator starts to move?
(b) during the first 1.00 s?
Here, what would be the answer of b? As the lift is going up shouldn't the weight be more than what it was initially?
