I started a thread called simple questions part 2 (https://www.physicsforums.com/showthread.php?s=&threadid=10036), and there is a section of questions that i still having trouble executing. First off with questions 32 and 33 I know which formula to use but i dont know how to calculate it on paper. For Question 33 The formula is d=1/2at^2 but 9000meters is the only figure given. and with question 32 and the formula being v=at, do I use the whole 14,000 secs or condense it to size for the calculating. with questions 31 Im not sure at all which formula to use. I am very lost.
