Mia tried. She froze at first. But then she remembered: total momentum before = total momentum after . She wrote that down. She didn’t finish, but she had started .

Priya compared her attempted solution to the official one. “Oh! I forgot that the rocket’s mass changes continuously. That’s why they use calculus, not just simple momentum.” Mia tried

That’s when their physics teacher, Dr. Evans, who had been pretending to organize equipment, walked over. “Priya is right,” he said. “Most students use past papers as a test. But the wise ones use them as a tutor. Let me show you a method.” She wrote that down

“Don’t time yourselves,” he said. “Don’t even worry about getting the right answer. Just write down anything you know. Draw the rocket. Write down momentum conservation. Even if you only get the first line—‘Let the exhaust mass be Δm’—that counts.”

Mia smiled. “So the ‘impossible’ problem is really just five small steps. I only missed step three because I didn’t realize the electric field was non-uniform.”
