Homework Statement
An elevator is moving upward at a constant speed of 2.50 m/s. A bolt in the elevator ceiling 3.00m above the elevator floor works loose and falls.
A. How long will it take the bolt to fall to the elevator floor?
I am not sure if I should do this relative to elevator or earth.
Homework Equations
Vb/g=Vb/e+Ve/g
Yb/g=Yb/e+Ye/g
3.The attempt at a solution
Vb/g=Vb/e+Ve/g
Vb/g= velocity of bolt relative to ground
Vb/e= velocity of bolt relative to earth
Ve/g= velocity of elevator relative to ground
Yb/g=Yb/e+Ye/g
Yb/g=position of bolt relative to ground
Yb/e= position of bolt relative to earth
Ye/g=position of elevator relative to ground
Vb/g=Vb/e+Ve/g
Vb/g=0+2.5m/s
Yb/g=Yb/e+Ye/g
Yb/g=3m+ 2.5m/s*t
Is this right so far? Where do I go from here? Thanks!
