Answer:
<em>The object with the twice the area of the other object, will have the larger drag coefficient.</em>
<em></em>
Explanation:
The equation for drag force is given as

where
IS the drag force on the object
p = density of the fluid through which the object moves
u = relative velocity of the object through the fluid
p = density of the fluid
= coefficient of drag
A = area of the object
Note that
is a dimensionless coefficient related to the object's geometry and taking into account both skin friction and form drag. The most interesting things is that it is dependent on the linear dimension, which means that it will vary directly with the change in diameter of the fluid
The above equation can also be broken down as
∝
A
where
is the pressure exerted by the fluid on the area A
Also note that
= 
which also clarifies that the drag force is approximately proportional to the abject's area.
<em>In this case, the object with the twice the area of the other object, will have the larger drag coefficient.</em>
65.5 mph I hope this helps and is correct
Answer:
Vertical height of the hill, h = 20.4 meters
Explanation:
Given that,
Speed of the bicyclist, v = 20 m/s
To find,
The vertical height of the hill.
Solution,
Let h is the height of the hill. When he approaches the bottom of the hill, the loss in kinetic energy is equal to the gain in potential energy. Using the conservation of energy as,



h = 20.4 meters
Therefore, the vertical height of the hill is 20.4 meters. Hence, this is the required solution.
