Answer- thermal energy :)
1.6764 meters. You can also google inches to meters for your answer.
Explanation:
The vertical component the velocity of the projectile is 15 m/s x sin 30 = 7.5 m/s.
The body is accelarating downwards at 10 m/s^2.
This means that every second its upward velocity reduces by 10 m/s.
So if the body is travelling upwards at 7.5 m/s then how long does it take for the velocity to become 0?
(7.5 m/s) / (10 m/s^2) = 0.75 s
The force of friction acts in the opposite direction that the object is moving, so friction slows down the motion of moving objects. Friction also produces unnecessary heat. For example, car engines become hotter because of friction.
Why would we assume that Earth is the center of the the Universe in the first place?
Besides the fact the Earth contains life, it is no different from any other planet that we have ever seen, nor is the solar system in which it resides. There is no reason in the first place to assume its placement in the universe is different either.
