Okay, so we have our altitude. Here are degree of 18 degrees. I mean, is that speed? The speed is equal to 275 feet for a second. And let's convert like B in terms of minutes, so that's gonna be 2 75 feet over seconds. And there 60 seconds in a minute. So we get 16 500 feet for a minute, okay? And in our altitude of the plane in a minute. And a sense of 80 degrees is people too. 16 500 times are fine of 18. The great, which were being 5098 0.7.

## Recommended Questions

When an airplane leaves the runway, its angle of climb is $18^{\circ}$ and its speed is 275 feet per second. Find the plane's altitude after 1 minute.

AIRPLANE ASCENT During takeoff, an airplane's angle of ascent is $18^\circ$ and its speed is 275 feet per second.

(a) Find the plane's altitude after 1 minute.

(b) How long will it take the plane to climb to an altitude of 10,000 feet?

An airplane is flying in still air with an airspeed of 275 miles per hour. If is climbing at an angle of $18^{\circ},$ find the rate at which it is gaining altitude.

ALTITUDE You observe a plane approaching overhead and assume that its speed is 550 miles per hour. The angle of elevation of the plane is $16^\circ$ at one time and $57^\circ$ one minute later. Approximate the altitude of the plane.

A plane takes off at an angle of $6^{\circ}$ traveling at the rate of 200 feet/second. If it continues on this flight path at the same speed, how many minutes will it take to reach an altitude of 8000 feet?

The angle of elevation to a plane approaching your home is $16^{\circ}$. One minute later, it is $57^{\circ}$. You assume that the speed of the plane is 550 miles per hour. Approximate the altitude of the plane.

An aircraft is climbing at a $30^{\circ}$ angle to the horizontal. How fast is the aircraft gaining altitude if its speed is $500 \mathrm{mi} / \mathrm{h}$ ?

If a jet airliner climbs at an angle of $15^{\circ} 30^{\prime}$ with a constant speed of 315 miles per hour, how long will it take (to the nearest minute) to reach an altitude of 8.00 miles? Assume there is no wind.

Angle of Elevation An airplane flies at an altitude of 5 miles toward a point directly over an observer (see figure). The speed of the plane is 600 miles per hour. Find the rates at which the angle of elevation $\theta$ is changing when the angle is (a) $\theta=30^{\circ},$ (b) $\theta=60^{\circ},$ and ( $) \theta=75^{\circ} .$

The shock wave off the cockpit of the FA 18 in Fig. $17-24$ has an angle of about $60^{\circ} .$ The airplane was traveling at about

1350 $\mathrm{km} / \mathrm{h}$ when the photograph was taken. Approximately what

was the speed of sound at the airplane's altitude?
