The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.

Question(1): a projectile is launched at an angle of 33 degrees up from level ground. if the initial speed of the projectile is 6.4 m/s how far from the launcher does it land? this is the set up that i used for the question: where i and o subscripts = initial split into the x and y direction where vix= vicos33degrees and viy=visin33degrees . x(t)= xi+vit+ 1/2at^2 and change inx= voit + 1/2at^2. v(t)= voy+at t=vosin33/ 9.8 delta x = 6.4 cos33 degrees + 1/2 (6/4) (6.4 sin 33 degrees) = 16.5 m. i was wondering if this set up was correct and if the answer i reached was accurate. my friend got a value about half this at 8.6 m so i'm unsure if i am correct.
