Find ratio of the sailing speed and non-sailing speed

Reference no: EM13246385

The wings on a stonefly do not flap, and thus the insect cannot fly. However, when the insect is on a water surface, it can sail across the surface by lifting its wings into a breeze. Suppose that stoneflies move at constant speed with the wings tucked in and at constant acceleration with the wings set. You time stoneflies as they move along a straight path of a certain length. On average, the trips each take 7.1 s with the wings set as sails and 25.0 s with the wings tucked in. (10 points)

What is the ratio of the sailing speed vs to the average non-sailing speed vns?

In terms of vs, what is the difference in the times the insects take to travel the first 2.0 m along the path with and without sailing?
