Explain how you would measure the width of the Grand Canyon from a point on its ridge.

Short Answer

Expert verified

The width of the Grand Canyon from a the point on its ridge will be:

distanceofthepoint脳tan胃.

Step by step solution

01

Step 1. Given Information

Assume a situation in which there is a Grand canyon of width x and there is a point on its ridge which is y units away from it.

02

Step 2. Calculation of the width

As we can see from the diagram,

In鈭�ABC,tan鈭�ABC=xy,So,x=y脳tan鈭�ABC.

So, if we have the distance of the point and the angle the point make with the edges of the canyon then we can easily find the width of the canyon using above fromula.

An object of mass m (in grams) attached to a coiled spring with damping factor b (in grams per second) is pulled down a distance a (in centimeters) from its rest position and then released. Assume that the positive direction of the motion is up and the period is T (in seconds) under simple harmonic motion.

(a) Develop a model that relates the distance d of the object from its rest position after t seconds.

(b) Graph the equation found in part (a) for 5 oscillations using a graphing utility.
