Question:
During the St. Pat?s celebrations. for reasons we will not discuss. a person is driving a car of mass m and speed v the wrong way out of the Physics Department parking lot. in the positively - direction. At the same time. a Iaw-abiding citizen in a pickup truck of mass M is traveling at unknown speed on Pine Street which makes an angle 0 with the x-axis. The car and the truck collide and stick together. The fused wreckage is skidding in the positive x-direction along the horizontal road surface for a distance D until it comes to a stop. Derive an expression for the coefficient of kinetic friction, ?. between wreckage and road. in terms of m, M , v, D , ? and constants. You may use. without proof. that the normal force magnitude is equal to the weight magnitude. (No people have been harmed in the creation of this test problem.)
