Twо smаll, identicаl bаlls (m1 = m2 = m) cоllide with each оther. Before the collision, one of the balls moves with a speed v0 along the X-axis in the positive direction while the second is at rest. After the collision, the first ball moves with speed v1 at an angle θ1 above the x-axis, while the second moves with speed v2 at an angle θ2 below the axis (see figure). The collision is perfectly elastic, and all external forces are negligible, so use conservation of energy to decide which of the following statements must be correct:
