An experiment is performed aboard the International Space Station to verify that linear momentum is conserved during collisions in a zero-g environment. The experiment involves a 3-D completely inelastic collision of three drops of honey. At the moment just before they all collide, the masses and velocities of the drops are m,-347 ,-139 m/s* m,-52.3 ,-(12.5 m/sj m,-76.5 g18.3 m/s v, - 13.9 m/slr What is your prediction for the speed, V, of the combined honey drop after the collision? Number m s

Answer 1

Here ,

let the speed of combined honey drop is V

m1 * v1 + m2 * v2 + m3 * v3 = (m1 + m2 + m3) * V

34.7 * 13.9 i + 52.3 * 12.5 j + 76.5 * 18.3 k = (34.7 + 52.3 + 76.5) * V

V = 2.95 i + 4 j + 8.6 k m/s

V = sqrt(2.95^2 + 4^2 + 8.6^2) = 9.9 m/s

the combined speed after the collision is 9.9 m/s
