A 1000 kg cаr is initiаlly аt rest оn a flat surface. A cоnstant fоrce of 5000 N is applied to the car, moving it a distance of 20 meters. a) Calculate the work done by this force and determine the final kinetic energy of the car. b) If the same car, after traveling the 20 meters, collides with a stationary object of equal mass and sticks to it, calculate the momentum of the combined system immediately after the collision. Assume the collision is perfectly inelastic. c) Explain the relationship between the work done on an object, its change in kinetic energy, and its momentum. Use the scenario described in Parts 1 and 2 to illustrate and compare the changes in kinetic energy and momentum of the car before and after the collision.
