I'm in a introductory physics course and I don't understand how to solve these problems.
I'm sorry, but the Rules of PF limit one problem for each HW thread. Also, you must show an attempt at solving a problem before you can receive help.
Flinging a bunch of problems at us with no work shown doesn't help you, and it only complicates trying to figure out where your real difficulty lies. :(
Sorry didn't knew. The problem is I don't know how to go about solving them, i try and I my mind goes blank. what's the process in solving them?
Pick one problem. Read the problem statement carefully. Write down what you know, and what is sought for the answer. Determine which motion formula or formulas might be applicable to solving the problem. Plug the known information into the problem and solve.
Follow these instructions. Feel free to post here in the homework section, but be aware that we require that the homework template be used. Especially the 'attempt at a solution' part. If you have absolutely no idea where to even begin, and you don't even know what equations you might need to use, then I'm afraid we cannot help you. We cannot teach you a subject from scratch.
Since this thread doesn't meet posting requirements for this area, I'm going to lock it.
