(3) Car A with a mass of 1250 kg is driving south at 25 m/s when it is struck by Car B having a mass of 1080 kg travelling west at 38 m/s. Determine the velocity and direction of the combined wreckage immediately after the
collision as well as the coefficient of friction needed to stop the wreckage after 89 m.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
