Review Taylor Example 2.5. Assuming you have two spheres made of the
same material
, but one has a larger diameter. When dropped in air, which one will reach the higher terminal velocity, the bigger one or the smaller one? Explain.
Suppose you are in an airplane flying in level flight and you want to drop something out of the plane so that it lands at a particular spot on the ground below. If there's no drag, you have to drop the object at a certain time in order to hit your target on the ground. If there is drag, do you need to drop later or earlier in order to hit the same spot on the ground? Please explain your reasoning
