State the hypothesis of this experiment

Which of the following is considered to be a vector?               a.  temperature    b.  velocity    c.  time    d.  mass

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

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?
