hi
plz solve this question:
" three particles are located at the vertices of an equilateral triangle of side 'a'. they all start moving simultaneously with a constant speed 'v' but move in such a way that the first particle is continually headed for the second, the second for the third and the third for the first. where and when will the particles converge?"
plzzz...... i need an urgent reply.

TAKE THE VELOCITY COMPONENTS OF ONE PARTICLE. USE COMPONENT SOLVE FOR VELOCTICY OF APPROACH WHICH COMES OUT TO BE (v-vCOS 60)=V/2.SO TIME WIL BE---------------------- T=2A/V ANS. HOPE IT IS RIGHT

purushotham

they meet at centroid of eqilateral traingle take the velocities component of approach as v-vcos60 ans 2a/3v
