a train is going 95mph you walk 5mph toward front of train. in relation to passanger seated on train how fast are you moving?
The seated passenger is fixed in the same frame of reference as the train. Therefore the walking passenger has a relative velocity of 5 mph relative to the seated passenger.
what formula to be used
what formula to be used
drwls,thanks i guessed that.
To calculate the relative velocity, you can use the formula for velocity addition: Vrel = V1 - V2.
In this case, V1 is the velocity of the walking passenger (5 mph) and V2 is the velocity of the train (95 mph).
So, the relative velocity (Vrel) is: Vrel = 5 mph - 95 mph = -90 mph.
The negative sign indicates that the walking passenger is moving in the opposite direction of the train. Therefore, in relation to the seated passenger on the train, the walking passenger is moving at a speed of 90 mph.
