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 three-fourths its altitude above the ocean. Assuming it takes the sound 2.18 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 It may be easier to calculate the altitude (part b) first. m/s (b) the altitude of the plane You know the time for the plane to fly the distance. If you know the speed of the plane from part (a) you can determine the numerical value of this distance. m

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

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 three-fourths its altitude above the ocean. Assuming it takes the sound 2.18 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
It may be easier to calculate the altitude (part b) first. m/s
(b) the altitude of the plane
You know the time for the plane to fly the distance. If you know the speed of the plane from part (a) you can
determine the numerical value of this distance. m
