Well in the first part of the problem (not shown) i found that the time for the bolt to fall to the floor is .782 seconds and according to an observer in the elevator the velocity would be 7.67 m/s (part 2). I don't see how an initial velocity of 2.5 m/s would fit into this problem.
Homework Statement
An elevator is moving upward at a constant speed of 2.50 {\rm{ m/s}}. A bolt in the elevator ceiling 3.00 {\rm m} above the elevator floor works loose and falls.
(Part C) What is the speed of the bolt according to an observer standing on one of the floor landings of the...
