Two identical arrows, one with twice the speed of the other, are fired into a bale of hay. Assuming the hay exerts a constant "frictional" force on the arrows, the faster arrow will penetrate how much farther than the slower arrow? Explain.

Step-by-step solution

Step 1 of 2:

The speed with which one arrow is shot is:

The speed of the other arrow is:

The constant negative acceleration due to the hay is a.

Now, the distances at which the 2 arrows come to rest are:
