A 1. 0-kilogram laboratory cart moving with a velocity of 0. 50 meter per second
A 1. 0-kilogram laboratory cart moving with a velocity of 0. 50 meter per second due east collides with and sticks to a similar cart initially at rest. After the collision, the two carts move off together with a velocity of 0. 25 meter per second due east. The total momentum of this frictionless system is.
