Bumblebees are skilled aerialists, able to fly with confidence around and through the leaves and stems of plants. In one test of bumblebee aerial navigation, bees in level flight flew at a constant 0.40 m/s, turning right and left as they navigated an obstacle-filled track. While turning, the bees maintained a reasonably constant centripetal acceleration of 4.0 m/s. Part A What is the radius of curvature for such a turn? Express your answer with the appropriate units. HA Value Units r 3= Submit Request Answer Part B How much time is required for a bee to execute à 90° turn? Express your answer with the appropriate units.
