Answer:-2.61 m/s Explanation: This problem can be solved by the Conservation of Momentum principle, which establishes that the initial momentum Po must be equal to the final momentum PI Po = P$ (1) Where: Po=mV. + NUE (2) PI = (m + M)V, (3) M = 1200kg is the mass of the first car V. = 20m/s is the velocity of the first car, to the North M = 1400kg is the mass of the second car Ua =-22m/s is the mass of the second car, to the South is the final velocity of both cars after the collision
(4) Isolating 5) (6) Finally: VI=-2.61m/s (7) This is the resulting velocity of the wreckage, to the south
