Step 1

Given information:

Mass of the car (m_{1}) = 1040 kg

Mass of the truck (m_{2}) = 4880 kg

Since given that north and east are considered as positive y and x axis respectively, then the south and west will be -ve y and -ve x respectively, hence the velocities can be written as:

Step 2

We know that the momentum is conserved in the collisions and in perfectly in elastic collisions the bodies stick together, hence we write:

Consider the change of momentum in x direction:

Step 3

Consider the change of mome...
