Find the relative change of kinetic energy during collision

Reference no: EM13978815

Two particles, m₁ = 2m and m₂ = m, are suspended on massless cords of the same length l = 1.00 m so that they touch each other (see Fig. below). Particle 1 is displaced to an angle of 30^o with the vertical and let go. After the particles collide, the cord attached to particle 2 comes to a maximum angle of 45^o.
