What will be the answer?
. A train is moving forward at a velocity of 2.0 m/s. At the instant the train begins to accelerate at 0.80 m/s2, a passenger drops a quarter which takes 0.50 s to fall to the floor. Relative to a spot on the floor directly under the quarter at release, it lands:
(A) 1.1 m toward the rear of the train.
(B) 1.0 m toward the rear of the train.
(C) 0.10 m toward the rear of the train.
(D) directly on the spot.
(E) 0.90 m toward the front of the train.

1 Answer
Option
Explanation:
Due to inertia of motion the quarter at the time of its release will have same velocity as that of the train i.e.2m/s. As the time of fall is
But the train will move with acceleration
Hence the quarter will fall
