Question

Plz solve it quickly​

Answer 1

Step-by-step explanation:

Let t be the time of journey

Distance moved by train: S=ut..(i)

Now since the compartment wa in motion its initial velocity is u

So distance travelled by compartment,

S'=ut−1/2at².(ii)

Distance between the train and compartment after it came to restS−S'=1/2 at²or S'=S−1/2at² from (i) S'=ut−1/2at²
