I am doing a lab and hoping I could ask for help with the last question.

Assuming a completely inelastic collision, where the next truck (new m1 assume to be the same kind of truck) slams into the car (new m2) and locks together, determine the final velocity of the car-truck system (heavy hits light).

What is the Mass (m1) of a full Tractor trailer in Kilograms ? _36,287_ kg

Speed of the truck before collision , v1 = _17_ m/s

What is the Mass (m2) of a Ford Focus in Kilograms ? ___298 kg

Speed of the Car before collision, v2 = _0_ m/s

Find the final speed of the truck-car group (use formula):
