Problema Solution
a girl is standing in an elevetor that is moving upward at a velocity of 12 ft/s when she drops her hand bag. If she was originally holding the bag at a height of 4 ft. above the elevator floor, how long will it take the bag to hit the floor?
Answer provided by our tutors
The time taken the bag to hit the floor is t
So the equation is
-4 = 12t - 0.5*32.15*t^2
So
t = 1.00 s
So time taken the bag to hit the floor is 1.00 s
