Best ResponseYou've already chosen the best response.1Using \[a = \left(\begin{matrix}Fnet \\ m\end{matrix}\right) = \left(\begin{matrix}W  R \\ m\end{matrix}\right)\] find Bronco's acceleration at each position. You need to know that his mass is 100 kg, so his weight is a constant 1000 N. Air resistance (R) varies with seed and cross  sectional area as shown.

Best ResponseYou've already chosen the best response.1Do you know any air resistance coefficient... Normally it's given as: Fdrag = A*C Where A is area of the person perpendicular to it's direction and C is some sort of air drag constant. Further on, do you know the area (A in previous formula) of mr Bronco?

Best ResponseYou've already chosen the best response.1I don't see how "Air resistance (R) varies with seed and cross  sectional area as shown. " Because it isn't shown

Best ResponseYou've already chosen the best response.1If R=0, as you show in your figure, and straight down (as in figure) ... the only acceleration he gets is gravitational acceleration (g=9.81 m/s^2)

Best ResponseYou've already chosen the best response.1so do u know how to calculate it now?

Best ResponseYou've already chosen the best response.1If there is no air resistance (R=0) and he will just jump straight down, his accelerations are: a(y) = 0 a(x) = 0 a(z) = g = 9.81 m/s (if z points down is positive, note SI units)

Best ResponseYou've already chosen the best response.1ok, so the acceleration is 0?

Best ResponseYou've already chosen the best response.1in horizontal direction, yes... it's 9.81 m/s2 in vertical direction (down)
