A 2571 kg van runs into the back of a 826 kg compact car at rest. They move off together at 8.5 m/s. Assuming the friction with the road can be negligible, find the initial speed of the van (in m/s).© BrainMass Inc. brainmass.com September 23, 2018, 11:48 pm ad1c9bdddf - https://brainmass.com/physics/conservation-of-momentum/initial-speed-van-161366

It finds the initial speed of the van, which runs into a car and moves together with the car afterwards. The solution is detailed and well organized.
