Momentum, vector addition question
Never mind, I converted 40km/hr to 12.5 m/s, should have been 11.1 m/s. That sucks, lost a lot of marks for it. I got 8.7 m/s as my answer.- ConfusedPhysics1234

Momentum, vector addition question
Hey, redid the algebra, got the same answer. What was your answer Simon Bridge?vfx = (1400 kg)(13.888m/s) / (1400kg + 2000kg) =5.7189 m/s vfy = (2000 kg)(12.5 m/s) / (1400kg + 2000kg) = 7.35294 m/s (5.71892 + 7.352942)1/2 = vf- ConfusedPhysics1234

Momentum, vector addition question
Homework Statement A car with a mass of 1400 kg is westbound at 50 km/h. It collides at an intersection with a northbound truck having a mass of 2000 kg and traveling at 40 km/h. What is the initial common velocity of the car and trucks after collision if it's an inelastic collision? Homework...- ConfusedPhysics1234
