will a golf ball of mass 45g and diamter 4.3cm reach terminal speed when dropped from a height of 25m? the drag coefficient is 0.35 and the density of air is 1.2kg/m^3.(adsbygoogle = window.adsbygoogle || []).push({});

using the formula [tex]v_t = sqrt(\frac{2*mg}{CpA})[/tex]

[tex]v_t = sqrt(\frac{2*(45g)(9.8m/s^2)}{(.35)(1.2kg/m^3)(0.043m)})[/tex]

so pluggeed that into my calculator, i found the terminal speed of 220.99m/s.

this is where i got stuck, how would i know if it reaches terminal speed or not when dropping from a height of 25m?
