A rescue plane flies horizontally at a constant speed searching for a disabled boat. When the plane is directly above the boat, the boat's crew blows a loud horn. By the time the plane's sound detector receives the horn's sound, the plane has traveled a distance equal to one-third its altitude above the ocean. Assuming it takes the sound 2.02 s to reach the plane, and taking the speed of sound to be 343 m/s, determine the following.

(a) the speed of the plane
m/s

(b) the altitude of the plane
m

Expert Solution

is the altitude of the plane.

is the distance traveled by plane after the horn is blown and it is received by the plane's detectors.

is the distance traveled by the soundwave.

=======

Given that by the time the plane's sound detector receives the horn's sound, the plane has traveled a distance equal to one-third its altitude above the ocean.

=========

Consider the soundwave

Speed = Distance/Time

==================

Consider the figure

Use Pythagoras' theorem

(b) ANSWER:

==========================

(a) Speed of the plane

Distance traveled by the plane,

Speed of the plane,

A cargo plane is flying horizontally at an altitude of 11.7 km with a constant speed of 900 km/hr when a large crate slides out of the rear of the plane. (a) How long does it take the crate to hit the ground? The acceleration of gravity is 9.81 m/s 2 . Answer in units of s. (b) What is the horizontal distance of the crate from the point it fell off to the point where it hits the ground?...

A bullet (m = 10 g) flies horizontally with an initial speed of v = 500 m/s and then embeds itself in a block of wood (m = 400 g) that is at rest on a flat surface. The surface has a coefficient of kinetic friction μk = 0.4. After the impact, how far does the block of wood slide? (a) 40 m (b) 800 m (c) 8 m (d) 80 m (e) 20 m

A plane flying horizontally at an altitude of 5 mi and a speed of 470 mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 7 mi away from the station. For full credit I expect to see a well-labeled picture. Show all work. Round your final answer to the nearest whole number. Do not round intermediate values. Include units of measure in your answer.

You drop a package from a plane flying at constant speed in a straight line. Without air resistance, the package will. (Hint: think about the velocity along the x direction, think about what type of motion you have along x direction). A) quickly lag behind the plane while falling. B) remain vertically under the plane while falling. C) move ahead of the plane while falling. D) not fall at all.
