Answer:
A. The bomb will take <em>17.5 seconds </em>to hit the ground
B. The bomb will land <em>12040 meters </em>on the ground ahead from where they released it
Explanation:
Maverick and Goose are flying at an initial height of
, and their speed is v=688 m/s
When they release the bomb, it will initially have the same height and speed as the plane. Then it will describe a free fall horizontal movement
The equation for the height y with respect to ground in a horizontal movement (no friction) is
[1]
With g equal to the acceleration of gravity of our planet and t the time measured with respect to the moment the bomb was released
The height will be zero when the bomb lands on ground, so if we set y=0 we can find the flight time
The range (horizontal displacement) of the bomb x is
[2]
Since the bomb won't have any friction, its horizontal component of the speed won't change. We need to find t from the equation [1] and replace it in equation [2]:
Setting y=0 and isolating t we get
![t=\sqrt{\frac{2y_0}{g}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7B2y_0%7D%7Bg%7D%7D)
Since we have ![y_0=1500m](https://tex.z-dn.net/?f=y_0%3D1500m)
![t=\sqrt{\frac{2(1500)}{9.8}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7B2%281500%29%7D%7B9.8%7D%7D)
![t=17.5 sec](https://tex.z-dn.net/?f=t%3D17.5%20sec)
Replacing in [2]
![x = 688\ m/sec \ (17.5sec)](https://tex.z-dn.net/?f=x%20%3D%20688%5C%20m%2Fsec%20%5C%20%2817.5sec%29)
![x = 12040\ m](https://tex.z-dn.net/?f=x%20%3D%2012040%5C%20m)
A. The bomb will take 17.5 seconds to hit the ground
B. The bomb will land 12040 meters on the ground ahead from where they released it
Condensation, radiation, convection, conduction are many ways heat is transferred from atmosphere to ocean. however heat comes from the sun then, to the atmosphere.
If you are talking about volume, then an easy way to measured the volume of a liquid would be with a graduated cylinder. A graduated cylinder is marked with volume units such as milliliter (mL) or the liter (L). One liter equals 1 thousand milliliters.
To measure the volume of a solid you use the formula V = (Length)(Width)(Height)
To measure the volume of a gas you use a graduated cylinder held upside down. At first the cylinder is filled with water. When air is blown into the cylinder, bubbles rise and push some water down. The volume of the water pushed down is equal to the volume of the gas that was blown in.
