For large objects, if the drag area increases, the terminal velocity will:
a. |
Decrease. |
|
b. |
Remain the same. |
|
c. |
Increase. |
With increase in area terminal velocity decreases. Thus, option a is correct.

During this process, does the puck's linear speed increase, decrease, or remain the same? A puck on a horizontal, frictionless surface is attached to a string that passes through a hole in the surface, as shown in the figure(Figure 1). As the puck rotates about the hole, the string is pulled downward, bringing the puck closer to the hole. O increases O decreases O remains the same Submit Request Answer Part B Complete previous part(s) Part During this process, does...
If a dense 20.0-kg object is falling in air at half its terminal velocity (drag force is proportional to the square of the object’s speed), what is the drag force on the object at this moment? a. 25 N b. 50 N c. 75 N d. 100 N e. 150 N
When government spending increases and taxes are increased by an equal amount, interest rates: A. Increase B. decrease C. remain the same. D. can vary wildly. Reset Selection
. Terminal velocity - free fall. Estimate (order of magnitude) the terminal speed vT of a typical human in free fall. Draw a free body diagram for the person falling at terminal velocity. Use the FBD, Newton’s second law, and the formula for air resistance (drag force) mentioned in class FD = 1/2 D ρ A v2 to find an expression for vT . Explain/justify any assumptions that you make (e.g., for quantities like the cross-sectional area A or the...
18. Jonah throws a rock off the Empire State Building, and it quickly reaches terminal velocity. Find the terminal velocity of the rock as it falls vertically, given the following information: drag coefficient = 0.75; air density = 1.2 kg/m3; cross-sectional area of the rock = 5e-5 m²; mass of the rock = 27 g. A B C 207 m/s 75 m/s 108 m/s 94 m/s 138 m/s E
Calculate the terminal velocity for a pollen grain falling through the air using the drag force equation. Assume the pollen grain has a diameter of 7 µm and a density of 0.3 g/cm3. If this grain is released from the top of a tree (height 11 m), estimate the time it will take to fall to the ground. Hint: The pollen grain will reach its terminal velocity very quickly and will have this velocity for essentially the entire motion. Your...
