Assume that the drop has reached terminal velocity. Express to 3 significant figures. terminal velocity of rain drop: = m/s m/s Take the size across of the drop to be 4.00 mm, the density of water to be 1.00×10³ kg/m³, the cross- sectional area of the drop to be r² where r is the radius of the drop, and the drag coefficient C to be 0.45. Take the density of air to be 1.21 kg/m³. Express to 3 significant figures. (c) Compare the answer in (b) to the terminal velocity for a typical droplet in a cloud. Take the size of the droplet to be 20.0 μm. Terminal speed of a droplet in a cloud = m/s.

Imagine that nitrogen and other atmospheric gases were more soluble in water so that the atmosphere of the Earth is entirely absorbed by the oceans. Atmospheric pressure would then be zero, and outer space would start at the planets surface. Would the Earth then have a gravitational field? (a) Yes, and at the surface it would be larger in magnitude than 9.8 N/kg. (b) Yes, and it would be essentially the same as the current value. (c) Yes, and it would be somewhat less than 9.8 N/kg. (d) Yes, and it would be much less than 9.8 N/kg. (e) No, it would not.
.An airport has occasionally been closed to large planes because of weather conditions that do not entail storms or low visibility. Instead, the conditions combine to create an unusually low air density. Explain why such an air density would make it difficult for a large, heavy plane to take off, especially if the runway were not exceptionally long.

By comparing the surface area of a sphere with its volume and assuming that air resistance is proportional to the square of velocity, it is possible to make a heuristic argument to support the following premise. For similarly shaped objects, terminal velocity varies in proportion to the square root of length. Expressed in the formula below, where L is length, T is terminal velocity, and k is a constant that depends on shape, among other things. This relation can be used to help explain why small mammals easily survive falls that would seriously injure or kill a human. T = kL0.5 (a) A 5 foot woman is 20 times as long as a 3-inch mouse (neglecting the tail). How does the terminal velocity of the woman compare with that of a mouse? Express to 2 decimal places.

Assume linear air re- sistance pv ft/s², taking p = 0.15 without the parachute and p = 1.5 with the parachute. (Suggestion: First deter- mine her height above the ground and velocity when the parachute opens.)
