kinematics

three particles start from origin with speed v1,v2,v3. v1 and v2 move along x and y axes respectively and v3 moves along a line which makes 30deg angle with positive x axis. determine v3 such that all three particles stay in one line at any given time

my approach is to plot them on coordinate plane .

they arent quite in a line in this but o hope u get the idea, now we cant just equate slopes for any two points. i dont have the answer to this question since i made it myself so anyone pls confirm if my method is correct

your approach is right equate the slopes taking t = 1 when they would've covered distance equal to their velocities
