physics. i need solve this Spaces correctly and tidy

Problem 1 (" :3) Consider two objects of masses m1= 9.004 kg and m2 = 3.703 kg. The first mass (mj) is traveling along the negative y-axis at 49.72 km/hr and strikes the second stationary mass m2, locking the two masses together. a) " .;What is the velocity of the first mass before the collision? m/s b ) ( : :3) What is the velocity of the second mass before the collision? Vm2 = 4 m/s c ) ( The final velocity of the two masses can be calculated using the formula number: (Note: use the formula-sheet given in the introduction section) d)
