- 7. The effects of atmospheric drag cannot be deglected, in general, on the dynamics of objects moving through the air. The drag force is found to be FD where p is the density of air, A is the cross sectional area of the object, v is the object's velocity, and Cp is the so called drag coefficient. For a baseball Cp is measured to be - .5ρA Cp υ?, .3. (a) If the baseball is launched vertically with a speed of 90 miles per hour, how high will it travel? How would the answer change ignoring air resistance? (b) What is the speed of the baseball when it comes back down? How would the answer change if there was no air resistance?
