An Escort and a Camaro traveling at right angles collide and stick together. The Escort has a mass of 1300 kg and a speed of 30 km/h in the positive x direction before the collision. The Camaro has a mass of 1700 kg and was traveling in the positive y direction. After the collision, the two move off at an angle of 55 o to the x axis. What was the speed of the Camaro?(in km/h)
