the position of a dragonfly that is flying parallel to the ground is given as a function of time by r=[2.90m+(0.0900m/s^2)t^2]i-(0.0150m/s^3)t^3j. (a) At what value of t does the velocity vector of the insect 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 acceleration vector of the insect? I just need help with finding the magnitude and direction of the acceleration vector of the insect thanks
