An elevator car whose floor to ceiling distance is equal to \( 3.8 \mathrm{~m} \), starts ascending with constant acceleration of \( 2.2 \mathrm{~m} / \mathrm{s}^{2} \), 4 second after the start a bolt begins falling from the ceiling of the car. The free fall time of the bolt is:
a. \( 0.800 \) second
b. \( 0.931 \) second
c. 1 second
d. \( 0.633 \) second
