While out exercising, and thinking about some of my favorite comic book heroes, I asked myself a question. **How does running 10 times faster affect someones body? **What kinds of things would happen to someones body?

To answer this question, we'll have to use one of Newton's energy equations. In terms of speed, **Kinetic ****Energy = 1/2 * Mass * V^2**

When someone says that a car traveling at 120 MPH will have double the impact as a car traveling at 60 MPH, they are wrong. The answer is actually **four times more impact energy! **In the kinetic energy equation, you can see that velocity squared is exponential. Therefore, if 60 MPH = V, and 120 MPH = 2* V, then 2 * V^2 = 4 * V.

That means if someone ran at 10 times the speed that they normally do, their body would have to withstand literally 100 times the impact! What does that mean? I estimate that you would literally need **100 times the durability just to run 10 times faster. **Therefore, your bones and muscles would be experiencing 100 times the impact it normally does and would have to be 100 times more stronger in durability.

I don't know the relationship strength has with durability and speed since I never studied biomechanics. But it would definitely be interesting to me to see how strong someone would have to be to literally run 10 times faster.
