1. The problem statement, all variables and given/known data A collision in Phystown is being analyzed by the O.P.P. accident analysis team. A 1000 kg Toyota known to be moving at 65 km/h [W] collided at an intersection with a 3000 kg SUV moving [N]. After the collision, the two vehicles "stuck" together and the police estimate that immediately after impact the Toyota-SUV wreckage moved at 45 km/h. Based on this information, what was the speed of the SUV before the collision? 2. Relevant equations mv1 + mv2 = v (m1 +m2) 3. The attempt at a solution I just plugged in values into the equation that i was given from the question... (1000)(-18.1) + 3000v2 = 12.5 (4000) -> i made E and N positive I was just wondering if i did this right! should i do components since i have directions in y and x directions? Thank you!
