A golf ball, initially at rest on the tee, 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 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/m³. a) 2.5 N b) 3.6 N c) 4.7 N d) 5.8 N e) 6.9 N f) 8.1 N 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 b) 32 m/s c) 35 m/s d) 41 m/s e) 48 m/s f) 102 m/s Short Answer Question} 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.)

A 44.0-kg child finds himself trapped on the surface of a frozen lake, 10.0 m from the shore. The child slips with each step on the frictionless ice and remains the same distance from the shoreline. Egged on by his parents, he throws a 0.750-kg ball he is carrying toward the center of the lake with a horizontal speed of 1.50 m/s, in the direction opposite that of the shoreline. a. Does the act of throwing the ball cause the child to move? If so, what are the speed and the direction of his motion with respect to the Earth? b. What are the forces acting on the child when he throws the ball?

A 0.0250-kg bullet is accelerated from rest to a speed of 550 m/s in a 3.00-kg rifle. The pain of the rifle's kick is much worse if you hold the gun loosely a few centimeters from your shoulder rather than holding it tightly against your shoulder. (a) Calculate the recoil velocity of the rifle if it is held loosely away from the shoulder. (b) How much kinetic energy does the rifle gain? (c) What is the recoil velocity if the rifle is held tightly against the shoulder, making the effective mass 28.0 kg? (d) How much kinetic energy is transferred to the rifle shoulder combination? The pain is related to the amount of kinetic energy, which is significantly less in this latter situation. (e) Calculate the momentum of a 110-kg football player running at 8.00 m/s.
