A 58.0 kg man stands on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.55 m/s in 1.25 s. It travels with this constant speed for the next 8.00 s. The elevator then slows down (undergoes a uniform acceleration in the negative y direction) for 2.25 s and comes to rest. What does the bathroom scale register during the first 1.25 s? Answer in units of N. (Hint: find the acceleration first.)
