Title: Relative Velocity Interception problems-Additional Math
Post by: AshWINNER on July 26, 2010, 07:12:07 am

Can anybody tell me how to find the speed and direction of a moving particle relative to another if the speeds of both are given are the distance north direction is given

For example:

Particle A is 30 m due north of Particle B. Particle P is moving at 5m/s in direction 030 degrees and particle A is moving at 7m/s in direction 090 degrees. Find the speed and direction of A relative to B.

I know it forms triangle but I dont know how to draw the velocity diagram or anything. Please help

Are you sure there are 3 particles and not two?

And are you sure you typed in the question right?
