Answer:
0.7864m
Explanation:
Ignore air resistance (the ball's horizontal speed stays constant), the time it takes for the ball to travel 1.95 m horizontally at the rate of 4.87 m/s.
t = 1.95 / 4.88 = 0.4s
This is also the time it takes to fall vertically with gravitational acceleration of g = 9.81 m/s2. We can use the following equation of motion to estimate the vertical distance:
The atmosphere is made up of layers which vary in temperature and other characteristics.
<h3>Layers of the atmosphere</h3>
The atmosphere is divided into several layers. The atmosphere refers to the thin layer of air that lies above the earth crust. The following describes the layers of the atmosphere.
- The troposphere refers to the layer where weather changes largely occur and clouds form.
- The stratosphere has an average temperature of about 270 K (−3°C or 26.6°F). The ozone layer is found in the stratosphere.
- The temperature in he mesosphere is about − 85°C (− 120°F).
- The thermosphere has a temperature of 200° C (360° F). The ionosphere is found within the thermosphere.
