The velocity of engine of the train is 24m/s & velocity of last compartment is 20m/s so find the velocity of middle point of train... |
|
Answer» Let the length of the train be =l We apply the equation of motion v2=u2+2al 2al=v2−u2 The acceleration is a=v2−u22l For, half the train, the length is =l2 and the velocity is =w Therefore, w2=u2+2a⋅l2 =u2+al =u2+v2−u22l⋅l =2u2+v2−u22 =u2+v22 So, w=√u2+v22 =22.09 |
