Two cars collide at an icy intersection and stick together, Ask an Expert

Academics

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1600 kg and was approaching at 7.00 m/s due south. The second car has a mass of 850kg and was approaching at 25.0 m/s due west.

(a) Calculate the final velocity of the cars. (Note that since both cars have an initial velocity, you cannot use Equations 7.6a and b. You must look for other simplifying aspects.)

Magnitude

m/s

Direction

° (counterclockwise from west is positive)

(b) How much kinetic energy is lost in the collision? (This energy goes into deformation of the cars.)
