Answer:
first is regular reflection and 2nd is irregular
Answer:
The speed of the stone when it is 4.66 m higher is 236.057 m/s.
Explanation:
Given the initial velocity and vertical distance, we can use the fourth kinematic equation () to find v final, or the v to the left of the equal sign. We know (initial velocity) is 24.7 m/s, y (change in vertical distance) is 4.66 m, and a is another way to write g (acceleration due to gravity), or 9.8 .
From here you could plug in the values and solve for v final, but to make the solving process simpler, we can simplify the given equation, <em>then </em>plug in the known values.
To isolate v final, we can take the square root of and do the same to the right side of the equation. Therefore, we can find v final with: , where v initial is outside of the square root because it squared...
If we plug in the known values to the simplified equation, we get:
The final answer is 236.057 m/s.
Answer: The satellite, if it is orbiting at a certain speed once launched into space, will continue to orbit at that same speed until it collided with some other force, such as debris or something along those lines. In space, with the amount of gravitational pull that surrounds the earth, once something falls into orbit, it will continue to orbit the same way as it began. The earth will continue to pull the satellites towards itself with the same amount of force, and so will keep its orbit consistent.
Explanation:
A hiker walks 200 m west and then walks 100 m north, the
resulting magnitude is 223 m. The direction can be solve using trigo function
sin angle = opposite/ hypotenuse. Which is equal to 26.6 degree. So the
displacement and direction is 223 m 26.6 degree North of west.
To solve this problem we will define the order of magnitude of both points, then we will obtain the radius and obtain the conclusion of the order of magnitude.
A nanosecond is one billionth of a second while and a millisecond is one millionth of a second
Therefore something that runs in nanoseconds is six times faster than something that runs in milliseconds
