Question
1.) An aircraft performs a maneuver called an aileron roll. Dujring this maneuver, the plane turns like a screw as it maintains a straight flight path, by using its ailerons to set the wings in circular motion. Due to structural strength, an airplane can only withstand an acceleration of 6.1m/s^2 on its wing tips. If the wing span is 6.0m, what is the shortest time it can make a full turn when it performs an aileron roll?
2.) The weight of a spaceman Speff, solely due to the gravitational pull of planet X at its surface, is 389 N. If he moves to a distance of 1.86x10^4km above the planet's surface, his weight changes to 24.31 N. What is the mass of planet X, if Speff's mass is 75kg?
Explanation / Answer
1)
x=ut+1/2at^2
6/6.1=t^2
t=0.99 seconds
2)N=389/24.31=16
sqrt N=4
F=GM1M2/R^2
So
Answer=2.96*10^24 kg
