The position of a dragonfly that is flying parallel to the ground is given as a function of time by r⃗ = [2.90 m + (0.0900 m/s^2)t^2] - (0.0150 m/s^3)t^3. (a) At what value of t does the velocity vector of the dragonfly make an angle of 30.0^∘clockwise from the +x-axis? (b) At the time calculated in part (a), what are the magnitude and direction of the dragonfly #x27;s acceleration vector? (Figure can #x27;t copy) Fig. E3.32
