An airplane is flying in a horizontal circle at a speed of 480 km/h (). If its wings are tilted at angle =40° to the horizontal

, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an "aerodynamic lift" that is perpendicular to the wing surface.

Answer:

R = 2162 m

Explanation:

When wings of the airplane makes an angle of 40 degree with the horizontal so here we can say that force due to air is having two components

F_y = mg

F_x = \frac{mv^2}{R}

now we know that

F_y = F cos40

F_x = F sin40

also we know that

v = 480 km/h

v = 133.3 m/s

now plug in all data in above equations

tan 40 = \frac{v^2}{Rg}

R = \frac{v^2}{g tan40}

R = \frac{133.3^2}{9.8 tan40}

R = 2162 m

What is the kinetic energy of a 144 gram baseball moving at a velocity of 38.7 meters per second?
gulaghasi [49]

Answer:

The kinetic energy of the baseball is  107.83 J

Explanation:

Given;

mass of the baseball, m = 144 g = 0.144 kg

velocity of the baseball, v = 38.7 m/s

The kinetic energy of the baseball is given by;

K.E = ¹/₂mv²

where;

m is mass of the object

v is speed of the object

K.E = ¹/₂(0.144)(38.7)²

K.E = 107.83 J

Therefore, the kinetic energy of the baseball is  107.83 J

How could you reorganize Table 2-2 so that the data would be more useful?
velikii [3]
First, I would make a copy of Table 2-2 with some color of ink
that's visible, to replace the current one printed in invisible ink. 

That change would immediately make the whole table more useful,
and I could go ahead and think about how to reorganize the data.

If the force of the sun and the earth is 3.5×10 to the power of 22 N, how far apart are they?
Jobisdone [24]

Gravitational force between 2 objects . . .

F = G · m₁ · m₂ / D²

-- You said that F = 3.5 x 10²² Newtons.

-- G = the gravitational constant = 6.67 x 10⁻¹¹ N m² / kg²

-- You want to find D .

F = G · m₁ · m₂ / D²

Multiply each side by D² . . .  D² · F = G · m₁ · m₂

Divide each side by F . . .  D² = G · m₁ · m₂ / F

So finally . . . D = √(G · m₁ · m₂ / F )

D = √(6.67 x 10⁻¹¹ N·m²/kg² · Earth mass · Sun mass / 3.5 x 10²² N)

<em>D = 4.37 x 10⁻¹⁷ · √(Earth mass · Sun mass) </em> meters
