box il you a to grade this scenario A golf ball, initially at rest on the tec, is hit by a golf club with mass 422 g that is initially traveling at 41.4 m/s. The golf ball has a mass of 45 g and radius of 2.1 cm, and is given a speed of 60 m/s during this partially inelastic collision Multiple Choice Questions (3 points each); 5) If the drag coefficient is 1, what is the drag force on the moving ball? You may assume the density of air is 1 kg/m'. a) 2.5 N c) 4.7 N e) 6.9 M b) 3.6 N d) 5.8 M 1) 8.1 N Score for this scenario / 12 6) What is the speed of the golf club after the ball is hit? Ignore any forces besides the force of the collision a) 18 m/s c) 35 m/s e) 48 m/s b) 32 m/s d) 41 m/s f) 102 m/s Short Answer Question (6 points): Suppose the golf ball is hit with an initial speed of 60 m/s at an angle of 21° above the horizontal. What is the maximum height it reaches? If the ball lands at the same height from which it was launched, how much time does it spend in the air? For this question, you assume may the golf ball follows projectile motion. (Note, this is not a good assumption.)
