mass to help you compare the speed of the pod after the collision to the speed of the space station after the collision?

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. when the carts collide, they hook together. assume that positive momentum is to the right. which graph best represents the momentum of both carts over time, before and after the collision?

An electron in an x-ray machine is accelerated through a potential difference of 1.00 × 104 v before it hits the target. what is the kinetic energy of the electron in electron volts?

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
