An airplane is flying in a horizontal circle at a speed of 490 km/h. If its wings are tilted at angle ɵ = 45° 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.
Answers
The radius of the circle in which the plane is flying is 1887 m.
What is aerodynamic lift?The aerodynamic lift is the force that keeps the aircraft flying in the air.
Let the aerodynamic lift be F1 sinθ= mv^2/R ---- (1)
and F1 cosθ= mg --------- (2)
Equating (1) and (2) and eliminating the mass;
R = v^2/ g tanθ
Where v = 490 km/h or 136 m/s
R = (136)^2/9.8 * tan 45
R = 18496/ 9.8
R = 1887 m

Answer:
0.1667Hz
Explanation:
by explanation frequency is given by 1/time
after carrying out the calculation of time we can easily get frequency.
time=speed/distance
=18/3

A twirler’s baton is 0.76 m long and spins around its center. the end of the baton has a centripetal acceleration of 47.8 m/s2. how long does it take the baton to complete one spin? 0.31 s 0.56 s 4.3 s 70 s
Answers
The time it takes the baton to complete one spin is determined as 0.56 s.
Time of motion of the baton
The time of motion of the baton is calculated as follows;
a = 4π²R/T²
where;
R is radius of the wire = ¹/₂(0.76) = 0.38T² = 4π²R/a
T² = (4π² x 0.38)/47.8
T² = 0.3138
T = 0.56 s
Thus, the time it takes the baton to complete one spin is determined as 0.56 s.

you are designing an airport for small planes. one kind of airplane that might use this airfield must reach a speed before takeoff of at least 27.8m/s and can accelerate at 2.00m/s a)if the runway is 150m long,can this airplane reach the required speed for take off?(in this case v=24.5 m/s) b) if not, what minimum length must the runway have(193m)
Answers
(a)The required speed for take off will be 24.49 m/sec.
(b)The minimum length must the runway have 193 m.
What is speed?Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while v for the final speed. its SI unit is m/sec.
(a)The required speed for take off will be 24.49 m/sec.
From the Newtons third equation of motion;
[tex]\rm v^2 = u^2+2as \\\\ v=0+2 \times 2 \times 150 \\\\ v=\sqrt{600}\\\\ v=24.49 \ m/sec[/tex]
Hence, the required speed for take off will be 24.49 m/sec.
(b)The minimum length must the runway have 193 m.
From the Newtons third equation of motion;
[tex]\rm v^2 = u^2+2as \\\\ (27.78)^2 = 0+2\times 2 s \\\\\ s=192.93 \ m[/tex]
Hence, the minimum length must the runway have 193 m.
