Two vehicles of masses m =1,830.1 kg and m2 =847.3 kg respectively, one moving eastbound and the other one moving westbound, collide head-on and become entangled (they move together after the collisions). If the magnitude of the velocity of the second object immediately before the collision is v2 =9.9 m/s and the magnitude of the velocity of the two objects after the collision is v = 4.9 m/s and they are moving eastbound, what was the magnitude of the velocity of the first block immediately before the collision? Hint: Please pay attention to the signs in your equations
