you are asked to reconstruct the conditions that led to a vehicle crash. Upon arrival at the scene of an accident between two vehicles (in this case a car and a truck), you discover that they have collided inelastically (i.e. they are stuck together). Based on a conversation with the two drivers involved (thankfully no one was injured), you know that the truck was traveling due east and the car was traveling due north prior to the collision (see diagram below). You don't trust either of the two drivers' claims of their respective speeds before the crash, so you need to use Physics to estimate these quantities. Your measurements of where the cars stop relative to where the crash actually occurred are indicated as L and 0 in the figure and table below. The coefficient of kinetic friction between the tires and the pavement is k. Assume the gravitational acceleration is g = 9.8 m/s². This problem is continued on the next page.
