An elevator car whose floor-to-ceiling distance is equal to 2.7 m starts ascending with constant acceleration 1.2 m/s2. 2s 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 ground.

An elevator car whose floor-to-ceiling distance is equal to 2.7 m star

1.	An elevator car whose floor-to-ceiling distance is equal to 2.7 m starts ascending with constant acceleration 1.2 m/s2. 2s 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 ground.
Answer» An elevator car whose floor-to-ceiling distance is equal to 2.7 m starts ascending with constant acceleration 1.2 $m / s^{2}$ . 2s 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 ground.
