You have two golf balls that differ only in their surfaces. One hasdimples, the other one is smooth. If you drop these ballssimultaneously from an airplane, which on will reach a greaterterminal velocity?A)The dimpled one.A)The dimpled one.
B)The smooth one.
C)They will reach the same terminalvelocity. Hint: In Fluid dynamics, Pay attention to the critical Reynoldsnumber.
