As your jet plane speeds down the runway on take off, you decide to determine its acceleration, so you take out your yo-yo and note that when you suspend it, the string makes an angle of 22 degrees with the vertical. What is the acceleration of the plane?
Homework Answers
The situation can be visualized as
From the diagram, at equilibrium
and
So, the acceleration of the plane is

A jet plane at take-off can produce sound of intensity 9.30 W/m2 at 30.4 m away. But you prefer the tranquil sound of normal conversation, which is 1.0 μW/m2. Assume that the plane behaves like a point source of sound. What intensity from the jet does your friend experience if she lives twice as far from the runway as you do?

A plane takes off and climbs to 3 000 m in five minutes at an angle of 8.28 degrees. When it reaches 3 000 m, the plane levels out and adjusts to its constant cruising speed of 500 km/h. At this height, there is a wind (a "jet stream") blowing at 100 km/h 30 degrees East of North. a) What is the magnitude of the plane's acceleration during the first five minutes of the flight? b) After reaching its cruising...

A physics student flying home for summer is waiting for the plane to take off. She is idly holding an old pocket watch from its chain, examining the watch. When the plane starts to accelerate for takeoff, she is holding the pocket watch steady by its 20.0 cm chain, looking at the ornate backplate of the watch. As the plane accelerates, the watch swings back and taps her on the nose. Pulling her head back, she digs out her protractor...

Suppose that you are holding a pencil balanced on its point. If you release the pencil and it begins to fall, what will be the angular acceleration when it has an angle of 10.0 degrees from the vertical? A typical pencil has an average length of 15.0 cmand an average mass of 10.0 g . Assume the tip of the pencil does not slip as it falls. What is the angular acceleration of the pencil when it makes an angle...

An object of mass m = 0.750 kg is suspended from the ceiling of an accelerating truck as in the figure below. Take a = 3.20 m/s. (a) Find the angle 8 (in degrees) that the string makes with the vertical. (b) Find the tension Tin N) in the string. What If? The truck returns to a constant velocity so that the mass hangs straight down inside the truck, whereby 9 = 0. Later, the truck carefully slows down. During...

You throw your phone straight out horizontally so that is leaves your hand with a velocity of 15.6 m/s forward. When the phone leaves your hand, its vertical height is 1 m above the ground. Once it leaves your hand, it begins to fall while moving forward due to gravity pulling it downward. a. What is the phones initial velocity in the horizontal (forward) direction in the instant it leaves your hand? b. What is the phones initial velocity in...
