A 20-Kilogram car traveling east at 6 meters per second collides with a 30-Kilogram car that is traveling west. If both the cars come to rest immediately after the collision, what was the speed of the west bound car just before the collision? A 0.025 -kilogram bullet is fired from a rifle by an unbalanced force of 200 newtons. If the force acts on the bullet for 0.1 second, what is the maximum speed attained by the bullet?
