Drag of a Sphere NASA
· Drag for a rough surface ball is shown on the figure at the top of the page by the dashed line. This effect produces a rather interesting result. There is a small range of Reynolds numbers for which the drag of a roughened ball is less than the drag of a smooth ball for the same diameter, velocity and flow conditions. The size and speed of a ...

learn moreDrag of a Sphere NASA
· The aerodynamic drag on an object depends on several factors, including the shape, size, inclination, and flow conditions. All of these factors are related to the value of the drag through the drag equation. D = Cd * .5 * rho * V^2 * A Where D is equal to the drag, rho is the air density, V is the velocity, A is a reference area, and Cd is the drag coefficient.

Speed Calculator is online 3 in 1 tool. You can easily calculate average speed having time and distance (given in different units of lenght miles, yards, meters, kilometers, inches etc.) but you can also compute traveled distance having time and average speed (given in different units of speed mph, kmh, mps yds per second etc.) and you can get travel time having average speed and distance.

This negative answer tells you that the yoyo is, on average, going down 3 inches per second.. Maximum and minimum velocity of the yoyo during the interval from 0 to 4 seconds are determined with the derivative of V(t): Set the derivative of V(t) — that''s A(t) — equal to zero and solve:. Now, evaluate V(t) at the critical number, 2, and at the interval''s endpoints, 0 and 4:
