We have three particles each of mass namely placed at the vertices of an equilateral triangle of side length
At , starts moving towards , starts moving towards , begins moving towards , each with a velocity .
Find the distance(not displacement) travelled by from till the time when all the three particles collide with each other.
Details and Assumptions
1)The velocity of A is always directed towards and is ,and similarly for the other two particles.
3)Ignore gravity and anything else.
