Expert Answer

Step 1

Given information:

Mass of the car (m1) = 1040 kg

Mass of the truck (m2) = 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:

Initial Velocity of the car (u) 1.75ỹ m/s
Initial Velocity of the truck (u2) = -8.052 m/s
Final velocity of the wreckage (v) -?

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:
