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 '25m/s'. Identify the calculation error, explain the correct problem-solving logic including the application of Newton's Second Law and kinematic formulas, and provide the correct answer. Additionally, provide two similar practice problems of comparable difficulty to help the student consolidate related knowledge points, ensuring they understand and master the solution method for such problems.
