1. ### As your plane circles an airport, it moves in a horizontal circle of radius 2150 m with a speed of 410 km/h. If the lift of the airplane's..?

centripetal force CF = m*V^2/r = m*410^2/(3.6^2*2150) =6.033*m weight W = m*g =9.806*m banking angle from vertical = arctan(CF/W) = arctan (6.033/9.806) = 31.34°

2. ### An airplane is flying in a horizontal circle at a speed of 103 m/s.?

(B) mv^2/r = m*6.45*g = (73.0 kg)(9.81 m/s^2)(6.45) = Around 4500 N but use a calculator. (A) v^2/r <= 6.45*g => r >= v^2/(6.45*g) = (103 m/s)^2/(6.45*9.81 m/s^2) = around 15m but use a calculator.

3. ### How fast would a golf ball fall if dropped from an airplane? In MPH. How long to reach that speed?

Drag force F: F = ρa*V^2/2*C*A being : C the drag coeff (0.5 for a sphere) A the cross-section area PI*r^2 in m^2 ρa the density of air equal to 1.25 kg/m^3 V the speed in m/sec weight force WF = 4/3*PI*r^3*ρb*g (ρb is the...

4. ### An airplane is flying in a horizontal circle at a speed of v = 625 km/h. If its wings are tilted at angle θ = 10° to the horizontal,?

625km/h * 1m/s / 3.6km/h = 173.6 m/s horizontal (radial, or centripetal) acceleration ax = v²/r vertical acceleration is zero, which means that ay = g where ax and ay are provided by the "lift." ax / ay = tanΘ = v² / gr r = v² / gtanΘ = (173.6m/s)²...

6. ### Physics and airspeed?

During the time the ball is falling, it has a vertical acceleration of 9.8 m/s^2. Use the following equation to calculate the time. d = vi * t + ½ * a * t^2 Since ball is moving horizontally, its initial vertical velocity...

7. ### An airplane makes a 90.0° turn while at a constant speed of 217.1 m/s. The acceleration is not constant and t = 20.9s?

I agree with your value for centripetal acceleration, but the implication here is that the plane is not following a circular path. Try calculating the acceleration in the original direction of travel as the component of velocity in that direction changes from 217.1 m/s to zero...

8. ### What is the acceleration of the airplane at t2 = 6.50 s?

Assume that the plane has velocity v₀ at the origin s = v₀t + ½at² 477.20 = v₀6.00 + ½a6.00² 477.20 - 18a = v₀6.00 79.533 - 3a = v₀ also 630.90 = v₀7.00 + ½a7.00² 630.90...
