a model airplane has a mass of... physics?

Question

a model airplane has a mass of .9 kg and moves at a constant speed in a circle that is parallel to the ground. Find the tension T in the guideline (length = 17 m) for speeds of 19 m/s and 38 m/s.

b) if the model airplane has a speed of 28m/s and a mass of .9 kg. The plane flies ona circle that is parallel to the ground. Find the Tension T in the guidelines whose lengths are 11 m and 22m

Answer 1

The model airplane will balance the force of gravity with lift from it's wings. As long as the guideline is level horizontal, then the force is the centripetal force

m*ω^2*r
since ω=v/r
the force is
m*v^2/r

r is the length of the guideline
r=17 m
m=0.9
for v=19 m/s
F=0.9*19^2/17
19 N

for v=38 m/s
F=0.9*38^2/17
76 N

b)
v=28
m=0.9
for r=11
F=0.9*28^2/11
64 N

for r=22
F=0.9*28^2/22
32 N

Answer 2

I easily have flown a type airplane that grew to become a million:20 scale. It grew to become extremely complicated interior the previous each and each little element. yet in any different case it grew to become very exciting. And as immediately as you get the carry of it, it turns into plenty greater advantageous exciting and exciting.
