Act as an experienced high school physics teacher and analyze the following student-submitted physics problem: The question is 'A 2kg object on a smooth horizontal surface is subjected to a 10N horizontal force. Calculate the velocity after 5 seconds.' The student's answer is '10m/s'. Please identify the logical flaws in the student's calculation, such as confusing acceleration with velocity or ignoring initial conditions. Then, provide the correct solution steps, including force analysis, acceleration calculation, and the application of the velocity formula, explaining why the student's answer is incorrect. Finally, provide a similar variation problem of comparable difficulty to consolidate the concept, along with its detailed solution.
