Seth is certainly the one who needs a long term care insurance.

A long term care insurance is a policy that covers the nursing bills for older citizens who are 65 years and above. It is an advance payment that covers about six or more years.

Such a policy is of more importance to Seth who has spent most of the money that he has made and keeps spending. He may not have enough money to cover his nursing bills in old age but Colin would depend on his long term savings.

a helicopter flies parallel to the ground at an altitude of 1/2 kilometer and at a speed of 2 kilometers per minute. if the heli

Murrr4er [49]

The Pythagoras' theorem and the uniform motion allows to find the answer for the rate of change of distance is

v = 32.3 m / s

The distance is the length of the segment that a white house wing with the helicopter, this can be found using the Pythagoras' theorem

R = $\sqrt{x^2 + y^2}$

Where R is the distance, x is the horizontal distance where the helicopter flies and y is the vertical distance that corresponds to the flight height

y = 500 m

Since the helicopter flies at constant speed, we can use the uniform motion relation

$v_h$ = $\frac{x}{t}$

x = $v_h$ t

Where $v_h$ is the speed of the helicopter and t is the time

We substitute

r = $\sqrt {(V_h \ t)^2 + y^2}$

Kinematics defines velocity as the change of position in the unit of time

$v = \frac{dR}{dt}$

$v = \frac{1}{2} \ \frac{2 ( v_h t) v_h}{ \sqrt{(v_h t)^2 + y^2} }$

$v = \frac{v_h^2 \ t}{ \sqrt{(v_h t)^2 + y^2} }$

This expression is the change in distance as a function of time for a given speed. In the exercise, this speed is requested for a time of one minute, for the helicopter speed of

v = 2km/min ( $\frac{1000m}{1km}$ ) ( $\frac{1 min}{60s}$ ) = 33.33 m / s

Let's calculate

v = $\frac{33.33^2 \ 60 }{ \sqrt{ )33.3 \ 60)^2 +500^2} }$

v = 32.3 m / s

In conclusion using the Pythagoras' theorem and the uniform motion we can find the answer for the rate of change in distance is

v = 32.3 m / s
