A runner starts from zero with a constant acceleration of 1.2 m/sec2. At the same time and same starting point, there is a bicyclist moving at uniform speed of 10 m/s. Who will reach the 200 meter line first? I know this is probably a pretty simple question for most of you but the unit squared is throwing me off. I figured to use the formula R=DT. This seems obvious but there again I just can't seem to incorporate the units squared into the grand scheme of things. Any help and maybe and an explanation would be greatly appreciated.
