The position of a dragonfly that is flying parallel to the ground is given as a function
Question:
The position of a dragonfly that is flying parallel to the ground is given as a function of time by r = [2.90 m + (0.0900 m/s2)t2]î – (0.0150 m/s3)t3ĵ.
(a) At what value of t does the velocity vector of the insect make an angle of 30.0o 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?
