A 1220 kg Triumph TR-8 traveling north at 37.5 km/hr crashes head-on into a 1930 kg...

A 1220 kg Triumph TR-8 traveling north at 37.5 km/hr crashes head-on into a 1930 kg Checker cab moving west at 80 km/hr. The two cars become tangled together.

Hint: Since directions are given by compass headings, the weight of each car is `into the page', and should not appear on your diagram.

a) What is their speed a moment after the collision?

b) If east is 0o, north is 90o, etc., at what angle are the entangled cars traveling just after their collision?

Please answer part b only.

Thank you for your help

    Two cars approach an ice-covered intersection. One car, of mass 1.11*103 kg, is initially traveling north at 12.1 m/s. The other car, of mass 1.70*103 kg, is initially traveling east at 12.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision.

    please answer (B) The plane of mass 5000 kg travels at 520 km/hr through still air due West. The plane then encounters a mysterious monster of mass 1350 kg traveling at 180 km/hr due East. The monster is stuck to the plane after they collide. At what speed and in which direction is the plane+monster traveling the instant after the collision? Ignore gravity during the collision and assume that there is no wind anymore. BY WAT F12 Priser De F2...
