Explanation: Velocity of Locomotive Overtaking the Boy
Let's assume that:
- The initial velocity of the locomotive is 0 m/s
- The uniform acceleration of the locomotive is a
- The velocity of the boy is constant at 2 m/s
- The time taken by the locomotive to overtake the boy is t seconds
- The distance covered by the locomotive during this time is d meters
Calculating the Distance Covered by the Locomotive
The distance covered by the locomotive is given by:
d = 1/2 * a * t^2
Calculating the Final Velocity of the Locomotive
The final velocity of the locomotive is given by:
v = u + a * t
where u is the initial velocity of the locomotive, which is 0 m/s
Substituting the value of t from the first equation in the second equation, we get:
v = u + 2a * d/a
v = 2d/t
Substituting Values and Solving
Now we can substitute the values given in the problem statement:
d = 2t^2
v = 2d/t = 4t
Therefore, the velocity of the locomotive when it overtakes the boy is 4 m/s.

Distance (s) =boy's velocity (v) ×time ( t )=2t . s(locomotive ) = ut + 1/2 at2 =2 t or ,0 + 1/2at2 = 2t or, at =4 . locomotive's velocity = u+ at = 0 + 4 = 4m/s
