Trying to find HOW to get the velocity.

[QUOTE="haruspex, post: 6471529, member: 334404"] There are some oddities with the question. We are given the "coefficient of friction". Assuming the wheels are free to rotate, the friction will be static, and its coefficient irrelevant. So presumably they mean the rolling resistance coefficient. It says the time to travel a stated distance is measured, but at that point in the text does not specify that time. Later, it gives the time to come to a stop. Are we supposed to assume these refer to the same event, i.e. it comes to a stop at the given distance? It seems so, since on that basis we can calculate the rolling resistance, and it is indeed the value given. So whoever set the question must have been aware it was redundant information. Unusual. .45cm. While I typed all that, [USER=499279]@caz[/USER] beat me to pointing out your error. [/QUOTE]
