Answer:
32.3 m/s
Explanation:
The ball follows a projectile motion, where:
- The horizontal motion is a uniform motion at costant speed
- The vertical motion is a free fall motion (constant acceleration)
We start by analyzing the horizontal motion. The ball travels horizontally at constant speed of
and it covers a distance of
d = 165 m
So, the total time of flight of the ball is
In order to find the vertical velocity of the ball, we have now to analyze its vertical motion.
The vertical motion is a free-fall motion, so the ball is falling at constant acceleration; therefore we can use the following suvat equation:
where
is the vertical velocity at time t
is the initial vertical velocity
is the acceleration of gravity (taking downward as positive direction)
Substituting t = 3.3 s (the time of flight), we find the final vertical velocity of the ball:
Heat is the answer but I need to use 20 characters to post :)
The conversion steps listed above in order from start to finish are already in an arranged form from 1-4.
<h3>What is a biosphere?</h3>
A biosphere can be defined as the part of the earth that supports life. These include :
The flow of energy through the biosphere includes
- Energy from the sun which is as a result of the nuclear fusion,
- the energy released is absorbed by plant chlorophyll,
- Chemical energy is released during respiration.
- Photosynthesis converts carbon dioxide and water into glucose and oxygen.

Answer:
Kinetic Generating Plants
Hydro-electric plants and wind-mills also convert energy into electricity. Instead of heat energy, they use kinetic energy, or the energy of motion. Moving wind or water (sometimes referred to as "white coal") spins a turbine, which in turn spins the rotor of a generator?
