A car with a mass of 1700 kg is traveling directly northeast (45° between north and east) at a speed of 14 m/s (31 mph), and collides with a smaller car with a mass of 1300 kg that is traveling directly south at a speed of 18 m/s (40 mph). The two cars stick together during the collision. With what speed and direction does the tangled mess of metal move right after the collision?

1) Two cars of the same mass collide at an intersection. Justbeforethe collision one car is traveling east at 55.0 km/h and the othercar is traveling south at30.0 km/h. If the collision iscompletelyinelastic, so the two cars move as one object after thecollision,what is the speed of the cars immediately after thecollision?

A 2400 kg car moving east at 10.0 m/s collides with a 3000 kg carmoving north. The cars stick together and move as a unit after thecollision, at an angle of 44.0° north of east and at a speed of6.18 m/s. Find the speed of the 3000 kg car before thecollision.
