A compressed spring is located between two stationary carts of the same mass. After burning through the thread that tightens the spring, the carts began to move in opposite directions with speeds equal in magnitude. What is the change in momentum of a system of bodies consisting of two carts? Neglect the frictional force during movement.
The change in momentum is equal to zero, since the carts of the same mass and with the same speed are moving in opposite directions.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
