An engine reaches its top speed from rest in 12.5 s. It is able to perform 250,000 J of work in that time. How much power does this engine have in that time?

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?
