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.)
J
The box is cubical, measuring 0.390 m on a side, and the thickness of the walls is 3.00 10-2 m. In one day, 2.90 106 J of heat is conducted through the six walls. Find out the thermal conductivity of the box.
