First off, I'm new to this forum so I would like to say hello to everyone on here. Secondly, I'm helping fellow law school friends out with a mock trial this coming week and was in need of some help. The fake trial is about a young man who hit a car on his motorcycle etc... lawsuit...etc.. I have determined that the young man weighed 210pds and was traveling on a 400pd motorcycle. He hit a stationary car and traveled 20 feet from the point of impact. How fast was he moving when he hit the parked car? I don't even know if there is a way to answer this, as I'm terrible with math. Rest assured, this is not a homework question or anything like that. I'm just trying to determine his rate of speed for the fake trial. I thought that this was a good thing to determine, as I imagine most people will not be inclined to use mathematical calculations in this case. If someone can answer this question and post the formula I would be thrilled. Thanks in advance.
