Question

The belly flop is often painful as a result of higher drag force acting on the body. Recalling that the drag force exerted on an object (like a human body) travelling at a speed v through a fluid is given by

Fd= (1/2) PA#(v^2)

Where A is the effective cross- sectional area of the object. # is the drag coefficient, and P is the density of the fluid. State which of the following best describes why the drag force is higher on the belly- flopping body.

1- A is larger

2- A and # are larger

3- v is higher

4- P is higher

5- A and v are higher higher.

6- # is higher

Explanation / Answer

2- A and # are larger
