Homework Help: Hi can i get some help

    1. The problem statement, all variables and given/known data

    It is a windless day at standard temperature and pressure. A golf ball of mass 45.5 grams and 4.25 cm diameter rests on a golf tee. It is hit by a golf club in an elastic collision with inclination pi/6 and force 16k Newtons. During flight, the air friction is 0.25 Newton seconds/meter. The ball lands inelastically in ...a sand pit at the same elevation as the golf tee.
    Q: What was the action of the golf ball ?

    2. Relevant equations



    3. The attempt at a solution

    What equations do you think might be relevant? Did you make an attempt at a solution?

    The problem statement appears incomplete, or at least has some typos in it. What do you mean by "the air friction is 0.25 Newton seconds/meter"? That's not the force of friction -- what measure of friction is it? And you need to define what you mean by "action" of the ball. What are the possible "actions"?
