Slightly away from the hand of his brother in the direction of motion of the train

(B) When the boy drops the apple,it possesses the same horizontal velocity as the train at that instant due to inertia of motion.Since the train is just about to stop,it is undergoing retardation (deceleration).As the apple falls,its horizontal velocity remains constant (neglecting air resistance),while the train's velocity decreases due to the retardation.Consequently,the apple covers more horizontal distance than the brother sitting in the train during the time of its fall.Therefore,the apple will fall slightly away from the hand of his brother in the direction of motion of the train.

$A$ boy sitting on the topmost berth in the compartment of a train which is just going to stop at a railway station,drops an apple aiming at the open hand of his brother sitting vertically below his hands at a distance of about $2 \ m$. The apple will fall:

A
Precisely on the hand of his brother
B
Slightly away from the hand of his brother in the direction of motion of the train
C
Slightly away from the hand of his brother in the direction opposite to the direction of motion of the train
D
None of the above

Relative Motion in One Dimension

Two particles are at rest on a straight track and they are separated from each other by $100 \ m$. They start their motion in the same direction,with the same acceleration $10 \ m/s^2$. Their relative displacement after $10 \ s$ will be

Two bodies start moving from the same point along a straight line with velocities $v_1 = 6 \, m/s$ and $v_2 = 10 \, m/s$,simultaneously. After what time will their separation become $40 \, m$?

$A$ motor car moving at a speed of $72 \, km/h$ cannot come to a stop in less than $3.0 \, s$,while for a truck,this time interval is $5.0 \, s$. On a highway,the car is behind the truck,both moving at $72 \, km/h$. The truck gives a signal that it is going to stop in an emergency. At what distance should the car be from the truck so that it does not bump into (collide with) the truck? The human response time is $0.5 \, s$.

$A$ $210 \ m$ long train is moving due North at a speed of $25 \ m/s$. $A$ small bird is flying due South a little above the train with a speed of $5 \ m/s$. The time taken by the bird to cross the train is $........ \ s$.

$A$ train is moving at a constant speed $V$. When its driver observes another train in front of him on the same track and moving in the same direction with constant speed $u$. If the distance between the trains is $x$,what should be the minimum retardation of the train to avoid a collision?
