Find the angle between forces of 41 pounds and 68 pounds given a magnitude of 87 pounds for the resultant force. (hint: write force one as a vector in the direction of the positive x-axis and force two as a vector at an angle θ with the positive x-axis.)

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.
