Watching a Helicopter Take Off At a distance of 58 ft from the pad, a man observes a helicopter taking off from a heliport. If the helicopter lifts off vertically and is rising at a speed of 45 ft/sec when it is at an altitude of 124 ft, how fast is the distance between the helicopter and the man changing at that instant? (Round your answer to one decimal place.)

To solve this problem we will apply the concepts related to classical mechanics, for which we will first consider the general equation that describes the movement of the body. From there, as we well know, we will obtain the derivative, which is equivalent to the speed of the body and the rate of change that is investigated in the problem.

Our values are given as,

We will start by defining the general height 'y' of the body at a reference distance of the lifting copter, given as

Differentiating both the sides we have

Now when the altitude of the copter is 124ft we have that

And,

Using these values at the derivative equation finally we have that

Therefore the distance between the man and the helicopter is increasing at the rate of 40.68ft/s

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

momentum of soft ball three times less than baskey ball
