Instantaneous Velocity - an overview ScienceDirect Topics

WebSolving for the different variables we can use the following formulas: Given v and u, calculate v Given initial velocity and final velocity calculate the average velocity. v ¯ = ( v + u) 2 Given v and v calculate u Given average velocity and final velocity calculate the initial velocity. u = 2 v ¯ − v Given v and u calculate v WebSolving for the velocity, we obtain vT = √2mg ρCA. Assume the density of air is ρ = 1.21kg/m3. A 75-kg skydiver descending head first has a cross-sectional area of approximately A = 0.18m2 and a drag coefficient of approximately C = 0.70. We find that vT = √ 2(75kg)(9.80m/s2) (1.21kg/m3)(0.70)(0.18m2) = 98m/s = 350km/h. robert herjavec cheated with actress https://cathleennaughtonassoc.com
