A 2590-kg van runs into the back of a 821-kg compact car at rest. They move off together at 8.5 m/s. Assuming the friction with the road is negligible, calculate the initial speed of the van.

m/s

The velocity of a 621-kg auto is changed from 10.0 m/s to 44.0 m/s in 70.2 s by an external, constant force.
