A birdcage with mass 22.5 kg at rest on a living room floor is acted on by a net horizontal force of 140N. what acceleration is produced. how far does the crate travel in 10.5 s?

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

Why do astronauts in the space shuttle weigh less?
