Answer:
<em>The range is 15.15 m and the time in the air is 1.01 s</em>
Explanation:
<u>Horizontal Motion</u>
When an object is thrown horizontally (with angle 0°) with a speed v from a height h, it follows a curved path ruled exclusively by gravity until it eventually hits the ground.
The range or maximum horizontal distance traveled by the object can be calculated as follows:
To calculate the time the object takes to hit the ground, we use the equation below:
The cannon is shot from a height of h=5 m with an initial speed of v=15 m/s. The range is calculated below:
d = 15.15 m
The time in the air is:
t = 1.01 s
The range is 15.15 m and the time in the air is 1.01 s
Answer:
During a lunar eclipse, the Moon turns red because the only sunlight reaching the Moon passes through Earth's atmosphere. The more dust or clouds in Earth's atmosphere during the eclipse, the redder the Moon will appear.
Force can be exerted into an object with out it moving, but if you were to move the object due to force it would be considered work. (yes, you can exert force without having the object moving)
Answer:
Because winding roads have a gentle slope on hills, so it's easy to climb it than a steepy.
Answer:
Fd
Explanation:
Work is force times distance. If you push on an object really hard but it does not budge, you have still performed no work on it, because anything times zero is still zero.
