If a woman pushes a box for 3 meters and does 600j of work, how much work does the box do?

falling water hydro = water .. spectcular places these plants are

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
