A lift ascends with an upward acceleration of 1.25ms^-2. At the instant its upward speed is 2.50ms^-1. A loose bolt falls from the ceiling of the lift, 2.75m from the floor.
Calculate:
(a) the time of flight of the bolt from the ceiling to floor
(b) the distance it has fallen relative to the lift shaft
Please help me. I have tried this question a few times and don't understand why i am getting it wrong, i think the aswer in the back of the book may be wrong. Can you please post your method and the answer please.
Thanx for your time and your brain cells.
