Question 10 [5 marks] You are playing a game of golf and because you aren't particularly good at it, your golf ball ends up in a lake (water temperature 20 deg C). The golf ball may be modelled as a sphere with a mass of 155g and a circumference of 22cm. The drag coefficient of the ball is CD-0.5. Your friend, who is much better than you, asks you what the terminal velocity of the ball is through the water. Which of the following is the terminal velocity? (answer accurate to within 10%) A) 1.98 m/s B) 2.54 m/s C) 3.79 m/s D) 1.26 m/s E) None of the above
