There is a bell at the top of a tower that is 45m high. the bell has a mass of 18kg. the bell has what energy

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?

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

When using the scientist method, which step comes last?
