if the flaps are fully retracted and theta is equal 0 that would mean the equation is equal to 0? is sin^2(theta) a trig identity? why am i get syntax error on calculator?
thanks, just what im looking for...
is sin theta the flap angle?
it says the change in drag coeffcient is equal to, so do i add this on to the original drag of the aerofoil?
Approximetly how much is the drag coefficient if orginally the coefficient is 0.02689. I know it depends on aircraft etc but im only looking a rough estimate.
i have produced a graph vertical against horizontal distance. However when the projectile angle is closest to angle of 0 it goes the furthest,what is the problem here. Is the horizontal speed for projectile with drag remain Vcos(theta)?
no it isnt, i woud like to plot the angle against displacement, how hard is that to do?
do i need to know the object mass and surface area (to work out Cd) to find it?
i used calculus to derive the equations knowing gravity and initial velocity and angle.
for drag:
I have calculated the horizontal and vertical distances but is there a way where i can combine these two and use theta in the equation to insert the projectile angle?
i am looking to find the projectile distance if an object (any object) was launched at 50 degrees considering the only information i know is u and v and theta (50)
can someone help me out on the formula i need in order to calculate the range?
