a 72 kg man stands on a spring scale in an elevator starting from rest the elevator ascends, attaining its maximum speed of 1.20 m per second in 0.8 hundred seconds it travels with this constant speed for the next 5 seconds the elevator then undergoes a uniform acceleration in the negative y direction for 1.50 s and comes to rest. What does the spring scale register(a) before the elevator starts to move?(b) during the first 0.800s?(c)while the elevator is traveling at constant speed?(d)during the time it is slowing down?
