Yue Cheng also had paper and a pen from Zhuo Xiaomao in his hand, but unlike Zhuo Xiaomao, he didn't write an array of formulas. Instead, after a brief pause, he directly wrote down a number and then watched Zhuo Xiaomao compute.
"Your formula is wrong," Yue Cheng pointed at the formula written on Zhuo Xiaomao's paper and said.
"Huh?!" Zhuo Xiaomao wore a defiant expression, as if to say, If you can't explain this properly, I'm going to tell my mom on you.
Yue Cheng didn't mind Zhuo Xiaomao's glare. He smiled, picked up his paper and pen, and said, "You must be looking at an old book, right? Let me derive it for you once more..."
Zheng Tan: "..." What exactly are you talking about? I don't understand a damn thing! Isn't this about two iron balls falling to the ground at the same time? What are you calculating now? Why are you bringing up height and classical physics? Free fall my ass! Mechanical motion, my foot! Formula derivation, crap!
