Homework Statement



If I pulled out in front of a car tht was going constant velocity of say 10m/s and I accelerated to 10m/s in 5 sec, is there a use for calculus to show the point of a collision if any or time safe distance required to avoid a collision?

If I understand your problem correctly (I'm not an English native speaker), the simple equations of uniform accelerated motions are sufficient. These equations are easily derived from calculus but can also be figured out intuitively.

The position of a body that undergoes uniform accelerated motion is given by
x=x_0+v_0t+\frac{1}{2}at^2
where x_0 and v_0 are the initial position and velocity.
If two bodies move with constant acceleration (which includes no acceleration), you just have to equate the two positions and carry out the math and you'll find out the point in which they collide.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
