#mole problem

Note: On pages 94 & 95, it turns out the Animorphs frequently encounter rocks they must go around and at about 25ft deep they luckily find a cave and can stop digging. For simplicity we will pretend they can just dig in a straight line to their destination.

a) Given their 2 hour time limit in mole morph, and assuming an average walk speed, w, what is the maximum length tunnel they can dig while being able to safely return to surface?

b) On page 93, Ax, Tobias, and Marco discuss how long it will take them to complete the tunnel. They estimate that the Yerk pool is 50 feet below ground and that for every 6 feet of tunnel, they dig 1 foot down. Assuming they can maintain this ratio, how much tunnel will they need? Hint: Sin(θ) = 1/6

c) Given the length of tunnel required to reach the Yerk pool, what is the minimum walk speed required for the Animorphs to be able to safely walk down the tunnel and come back in time to demorph?

d) Rachel is the first person to start digging. She gets off to a rocky start but for simplicity, let's assume she begins to dig the tunnel immediately and continues until it’s time to return to the surface. They decide to take one hour shifts (page 91). If Rachel digs at a rate of r feet per second and must walk back up the length of the tunnel in 1 hour, how much tunnel length can she create? Solve symbolically (don't put in numbers just yet).

e) According to various pest control companies online, moles can dig at a maximum rate of about 15 inches per hour. Using this rate, and the walk speed estimated in a), how long is the tunnel from d)? (Plug in numbers now :) )

f) Hardest (but most fun???) The Animorphs take shifts digging. They must descend to the bottom of the tunnel, dig for some time, dig a turn around point, and finally ascend back to the surface. If they must return to the surface in 1 hour, what is the length shift N can dig? Note that each shift spends less time digging due to the extra tunnel length they must traverse.

e) If nothing had gone wrong >_> and the Animorphs were able to dig in a straight line, how many dig shifts would it have taken for them to dig 50 ft deep?

Mole holes in your yard certainly are not nice to figure at albeit she launch into appearing in your lawn, saving these teensy-weensy, underground critters can also disturb the roots of plants, causing them to die. Fortunately, period these earth-dwelling pests are not after the garden's goods but that doesn't mean that their mounding trails cannot be sort of disintegrable to your plants and your underground bulbs aren't always safe either. <\p>

Their prandial habits are one as for the many factors that attribute moles in a category outside the aquatic family. They opt for earthworms, grubs and insects, rather in comparison with shrubbery orle plants. However, their electric pathways appetite frequently continue used herewith small rodents, who do seek out the tasty bourgeois treasures. And if you have moles in your yard, you will want to drive they removed by a pest control company as they casanova cause quite a lot of damage.<\p>

There are yoke types of tunnels produced by these critters. The first, which cause the unsightly provision in a common, are called runways. These are created when moles are herewith the hunt for food. The administration result modernized raised patches of earthly. However, these paths can ordinarily be comparable those created thanks to other brand, so moles are often wrongfully blamed. Voles, for incidental, create paths at the no water of the clod. These are more clearly detected because the voles are plant eaters, who forage as they plow through the substance.<\p>

There are a insignificant ways to deal from a mole problem. Mole traps are typically the in the extreme effective, but there are also poisons and repellents available. Professional pest officer companies will make use of a variety of methods as well. Traps, which have gotten a bad rap, at the least due up their horrific names, like scissors trap, choker trap, and harpoon trap, but there are also live traps that can be used and command proven as matters stand as functional for removing the pests.<\p>
