Two cars collide at an icy intersection and stick together afterward. The rst car has a mass of 1250 kg and was approaching at 100 mfs due south. The second car has a mass of ?50 kg and was approaching at 19.0 mfs due west. {a} Calculate the nal velocity of the ca rs. {Note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the x-axis and yaxis; instead, you must look for other simplifying aspects..] Magnitude E m Direction E 55' {counterclockwise from west is positive} {b} How much kinetic energy is lost in the collision? {This energy goes into deformation of the ca rs.} :J
