A 1500- kilogram vehicle traveling at a 15 meters per second crashes into a car with a mass of 2500 kilograms. After the collision both vehicles are locked together and slide. Eventually, both cars that were locked together were brought to rest by a force of Kinetic Friction as the rubber tires slides across the dry, level, asphalt road surface. [Show all work including the equations and substitutions with units] ∙ Calculate the speed of locked-together cars immediately after the collision.
.Calculate the magnitude the magnitude of the frictional force that brings the locked together vehicles to rest.
