    Four Vector Analysis: Calculating Particle Velocity and Ratio in Particle Decay

    A particle of rest mass Mo is at rest in the laboratory when it decays into three identical particles, each of rest mass mo. Two of the particles (1 and 2) have velocities and directions as shown. [1 is 3c/5 at -90degrees, 2 4c/5 at 180degrees] (a) Calculate the direction and the speed of...

    When should a coastguard cutter start out to intercept a ship?

    That's good; now you want x to be a minimum to get that particular point so take the derivative - remember at a minimum the derivitave = 0. A little trigonometry and the angles dissappear.
