Standard Airplane Propeller
General Physics Help (centripical acceleration)?
In civil aviation, a standard turn for level flight of a propeller driven airplane is one which the airplane makes a complete circular turn in 2.0min. If the plane's constant speed is 180 m/s, what is the radius and the centripetal acceleration of the plane.
I keep trying to use the equation Ac=(V^2)/(r) = rw^2 but nothing is coming out to be a logical answer. help please
a = v^2 / r
We have two unknowns in this equation. What we could do is express velocity in terms of circumference/period using the given information to find the radius first.
v = circumference / period
where period is 2.0min = 120s
circumference is 2pi*r
so we have v = 2pir/120s = pi*r/60s
So we have velocity = 180m/s = pi*r/60s we can solve for r
r = 180m * 60s / pis = 10800m / pi
Then you can plug this into a = v^2 / r to find the centripetal accel

what is Centripetal acceleration?
can you explain what centripetal acceleration is? and then show me in this example problem...i'm lost.
in civil aviation, a standard turn for a level flight of a propeller driven airplane is one in which the plane makes a complete circular turn in 2.0 min. If the plane's speed = 180 m/s, what is the radius of the circle? What is the centripetal accel. of the plane??
heres the web link with the full explanation.
http://en.wikipedia.org/wiki/Centripetal
it is the acceleration that pulls or pushes you toward the center of the circle that you move around and its calculated with (v^2)/r. in the example they aks for centrepital accel but you cant find it until you first find r, radius. change mins to seconds because speed uses seconds in its denominator. 2 mins is 120 seconds. now find circumference of the circle and set it equal to two-pi-r. circ = 120x180=21600 meters.
seconds has canceld out because it was in the numerator of the 120seconds and in the denominator of 180meters per second. 21600=2piR. now find R. pi is 3.12 so r is 3439 meters. centrepital is v(v)/r. v is 180
