[ QUOTE ] [ QUOTE ] [ QUOTE ] [ QUOTE ] A man drops his prize golden elephant statue (10 kg) out a window by mistake. Immediately after realizing his mistake (5 seconds later), the man (100 kg) in a lapse of judgment dives out the window to save his statue. Will he catch the statue in time? If not, how much will he miss it by? Answers below in green: <font color="green"> No, 5 second</font> [/ QUOTE ] you have to specify a falling distance for that question not to be way too easy. any decent test taker with no knowledge of physics should be able to figure that out based on the info given. [/ QUOTE ] I'll show my stupidity. I have hardly even any high school physiscs but this seems counter intuitive to me. Wouldn't the objects mass density be a a factor causing the, most likely, compact elephant thing to fall faster? [/ QUOTE ] no. you never got to throw a bowling ball and an egg out of the window in school? [/ QUOTE ] I must've been sick that day. [img]/images/graemlins/smile.gif[/img] I have however thrown a feather and a stone out a window and I swear to the stone dropped faster. Is the object's shape relevant? God, I feel like a fourh grader. [/ QUOTE ] the reason they fall at different speeds is wind resistance. In a vacuum the feather and the stone would fall at the same speed. |
