An elevator car with a floor-to-ceiling distance of 2.7m starts ascending with constant acceleration 1.2m s−2. Two seconds after the start, a bolt begins falling from the ceiling of the car. Find the following. Take g=9.8m s−2.
(a) The time after which the bolt hits the floor of the elevator.
(b) The net displacement and distance travelled by the bolt, with respect to Earth.
