You hear the sonic boom of a high-speed jet plane exactly 2.80 s after it passes directly overhead in level flight. At the time you hear the boom, you see the plane at an angle of 30.0 o above the horizon. Assume that the speed of sound at the altitude of the plane is 325 m/s. How fast is the plane traveling? What is the altitude of the plane?

You hear the sonic boom of a high-speed jet plane exactly 3.00 s after it passes directly overhead in level flight. At the time you hear the boom, you see the plane at an angle of 21.0 o above the horizon. Assume that the speed of sound at the altitude of the plane is 325 m/s. How fast is the plane traveling? What is the altitude of the plane?

when a figher jet travels faster than sound it generates a sonic boom shock wave in the shape of a cone. if the plane is flying at a constant altitude, this cone intersects the ground in the shape of one branch of a hyperbola. suppose a jet is flying north at level altitude and at a speed of 500 m/s ( which is a supersonic speed). in this model let the position of the jet be the origin. the vertix...

A jet plane passes over you at a height of 4990 m and a speed of Mach 1.75. (a) Find the Mach cone angle. (b) How long after the jet passes directly overhead does the shock wave reach you? Use 331 m/s for the speed of sound.

Sound of an Airplane: It is a common experience to hear the sound of a low-flying airplane and look at the wrong place in the sky to see the plane. Suppose that a plane is traveling directly at you at a speed of 200 MPH and an altitude of 1800 ft, and you hear the sound at what seems to be an angle of inclination of 21. At what angle 0 should you actually look in order to see the...

1. A bat emits a sound at a frequency of 12 kHz as it approaches a wall. The bat detects beats such that the frequency of the echo is 860 Hz higher than the frequency the bat is emitting. The speed of sound in air is 340 m/s. The speed of the bat is closest to 2. A supersonic plane passes overhead at a speed of 823 m/s. If you hear the sonic boom (shock wave) 4 s after the...

1. A jet plane passes overhead at Mach 2.5. The jet is flying at an altitude of h = 8000m. Assuming that the speed of the sound is 340 ms-1. (a) Compute the shockwave angle (Mach cone angle) of the moving jet. (b) How long does it take for the shockwave to reach the observer on the ground?

A high-performance jet plane, practicing radar avoidance maneuvers, is in horizontal flight 40.0 m above the level ground. Suddenly, the plane encounters terrain that slopes gently upward at 4.90°, an amount difficult to detect (see the figure). How much time does the pilot have to make a correction to avoid flying into the ground ( s)? The speed of the plane is 1150 km/h.
