In the vertical jump, an athlete starts from crouch and jumps upward to reach as high as possible. Even the best athletes spend
little more than 1.00s in the air (thier "hang time"). Treat the athlete as a particle and let ymax be his maximum height above the floor. To explain why he seems to hang in the air, calculate the ratio of the time he is above ymax /2 to the time it takes him to go from the floor to that height. You may ignore air resistance.

Answer:
minimum interface length = 1.36 mm
Explanation:
given data
weight of the bug = N
solution
we will apply here Surface Tension formula that is
Surface Tension ,σ = Force ÷ length ........................1
and we consider here surface tension for water is 7.34 × N/m
so that here minimum interface length needed to support the bug is
minimum interface length = Force ÷ σ
minimum interface length = ÷ 7.34 ×
minimum interface length = 1.36 mm
