A 5 kg block sitting 10 m above the Earth falls to the ground. What is the velocity of the block right before it hits the Earth?

none, its a machine

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

it doesn't. it was imagined up in the middle ages.
