Problem 1.15

Task:

An elevator car whose floor-to-ceiling distance is equal to \( 2.7 \) m starts ascending with constant acceleration \( 1.2 \) m/s\( ^2 \); \( 2.0 \) s after the start a bolt begins falling from the ceiling of the car. Find:

 (a) the bolt's free fall time;

 (b) the displacement and the distance covered by the bolt during the free fall in the reference frame fixed to the elevator shaft.

Solution:
