Asked by Faoruk
A car and an attached trailer have a combined mass of 3,000 kg. The car and trailer are moving on the highway at a velocity of 25 m/s. After going over a small bump in the road, the trailer detaches from the car. If the car’s speed after separation is 27 m/s and its final momentum is 35,000 kg m/s, what are the masses of the car and trailer, respectively?

initial momentum=final momentum
3000*25=Mc*27+Mt*Vt
35000=Mc*27 solve for mass car
but Masscar+masstrailer=3000 solve for mass trailer.
3000*25=Mc*27+Mt*Vt
35000=Mc*27 solve for mass car
but Masscar+masstrailer=3000 solve for mass trailer.
