Question

Three carts of masses 4kg, 10 kg, and 3 kg move on a frictionless horizontal surface with initial speeds of 5 m/s, 3 m/s, and 4 m/s. If the carts all stick together after the collisions, what will be the final velocity of the combined mass?

Help ASAP please. Step by step to get the answer

add the initial momnetums. Final momentum = (4+10+3)V solve for V
