Question

20m/s 10m/s A sudden breeze hits a 1-kg squirrel while he is in flight. The squirrel arches his "wings" to create an airflow speed above his wings of 20 m/s and an airflow speed beneath his wings of 10 m/s ( air = 1.29 kg/m3). The surface area of the squirrel's wings is 0.06 m2. What is the magnitude of the net vertical force on the squirrel? 0 1.81 N 03.87 N 05.93 N O 11.61 N 021.4 N

Answer 1

Answyo Bernoullis canation Ighi Pzt 1 1 V tfighe pit t f Viet Vi Where ve P2-Pi = 1 11,2 - I like 2 V2 2 BP =) 2 the wing ļ Evie vi Cohene V, - velocity of air flow above ੧੦ms V₂ ) velocity fair flow below the wing= lomls Sop f) density of air (1.2kg / m3) pressure difference -> izkg [00)-(1014) :-) 1.29x [400 - 100

A =) 19.3.5 malagon/s Where p=E fonce form air pressure (P) X (193.5 ( o . -olme) 11.610 force of gravity gravity on sanirred Eg = m(s) ?? (kg) (g.omlee) Nel -) 9.8W force -) 11.61 N -9.8W 11.81W
