The two ends of a train moving with uniform acceleration pass a certain point with velocity u and v. Find the velocity with which the middle point of the train passes the same point.

Text Solution

Verified by Experts


Between A,B : `(v^1)^2-u^2 =2a` s/2
Between B,C : `v^2-(v^1)^2`=2as/2
`rArr (v^1)^2-u^2=v^2-v^12`
`2(v^1)^2=v^2+v^2`
Velocity at mid point is `v_1=sqrt((u^2+v^2)/2)`
