This is the problem. I 'll translate detail into English.
The 1-kg mass is hang by spring, of which constant is k. The 2-kg mass is hang with the rope suspending the ceiling as shown in the picture. If the rope is instantly cut, what is the initial acceleration of the 2-kg mass?
Please tell me the answer and how to solve this problem.
Moreover, please tell me which chapters of physics should I study in order to solve this type of question more fluently.
Thank you in advance :]
