    Welcome to PF, Norules!

    Unfortunately, we have rules here, Norules. If this is a homework question you should post in the homework board and use the template.

    It is difficult to figure out what the question is let alone what you are doing. Please state the question and explain your answer. Then we may be able to help you out.

    BTW, if you are trying to use conservation of kinetic energy here, it will not work in this collision.

    This is no homework question and I am well aware of the regulations in this forum ,it is a question that i found in my university's resource center in preparation for my test. You mentioned you did not fully understand the question well that' all there is to it and I have attached a file(.docx) of the question please check.
