2017 · 9 Apr · Shift 1 · Q51

JEE MainPhysicsCenter of MassMCQ+4 / −1
Two particles A and B of equal mass M are moving with the same speed υ\upsilonυ as shown in the figure. They collide completely inelastically and move as a single particle C. The angle θ\thetaθ that the path of C makes with the X-axis is given by : JEE Main 2017 (Online) 9th April Morning Slot Physics - Center of Mass and Collision Question 105 English
