10. as the text discusses, the conservation of linear momentum is applicable only when the system of objects is an isolated system. which of the systems listed below are isolated systems? 1. a ball is dropped from the top of a building. the system is the ball. 2. a ball is dropped from the top of a building. the system is the ball and the earth. 3. a billiard ball collides with a stationary billiard ball on a frictionless pool table. the system is the moving ball. 4. a car slides to a halt in an emergency. the system is the car. 5. a space probe is moving in deep space where gravitational and other forces are negligible. the system is the space probe. (a)only 2 and 5 are isolated systems. (b)only 1 and 3 are isolated systems. (c)only 3 and 5 are isolated systems. (d)only 4 and 5 are isolated systems. (e)only 5 is an isolated system.
