The discussion revolves around two problems involving a 50-N force acting on a 2-kg object and a crate, both starting from rest. The first problem asks for the rate of work done after 2 seconds, while the second problem inquires about the rate of work done when the object has traveled 2 meters.
The conversation includes attempts to clarify the problems and the calculations involved. Some participants have provided answers but are unsure of their correctness. There is a clear indication that multiple interpretations of the problems are being explored, and guidance has been offered regarding the need to show work.
Participants are reminded that solutions should not be handed out directly, and there is an emphasis on understanding the underlying principles rather than just obtaining answers.

i have here an answer and am not sure if it's correct; for problem a, 2500watts., and for problem b 490watts.., am i correct? :)
Pengwuino said:We don't just hand students solutions. You have to show your work. The two problems do not have the same solution.
