Answer:

- 0.8333 m/s^2

Explanation:

the equation for calculating acceleration that I have used is

(V2-V1)/t

where V2 is the final recorded velocity and V1 is the initial velocity and t is the duration of the acceleration.

which you plug the numbers in (15 - 25)/12 = 10/12 and because you are slowing down, it should be negative

I am in highschool honors physics so I am not college leveled, I might be wrong but I hope this is useful,

Review 1: A plane is located x = 40 miles (horizontally) away from an airport at an altitude of h miles. Radar at the airport de
-Dominant- [34]

Explanation:

Let h is the height of the plane above ground. x is the horizontal distance between the ground and the airport. Let s(t) is the distance between the plane and the airport. So,

s(t)^2={h^2+x^2}...........(1)

Given, h = 4, x = 40 and s(t) = -20 mph

Differentiate equation (1) wrt t

2s(t)s'(t)=2x(t)x'(t)

x'(t)=\dfrac{s(t)s'(t)}{x(t)}

When x = 40, s(t)=\sqrt{40^2+4^2}=40.19\ m

x'(t)=\dfrac{-240s(t)}{x(t)}

x'(t)=\dfrac{-240\times 40.19}{40}

x'(t)=-241.14\ m/s

So, the speed of the airplane is 241.14  m/s. Hence, this is the required solution.
