Jordan noticed something else. “Look at this—the first two marks are just for defining symbols and drawing a diagram. I skipped those. But they’re free points.”

“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.” senior physics challenge past papers

Mia took a deep breath. She remembered Dr. Evans’ three columns. She wrote down what she knew. She drew the diagram. She took the first small step. Jordan noticed something else

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 . But they’re free points

“These problems look impossible,” Mia whispered, pointing at a question about a charged particle spiraling in a magnetic field. “I don’t even know where to start.”
