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.
In the textbook the kind of idealized object that described in section on radiation laws that it absorbs all the radiation falling for it because it is not giving off any radiation on its own. And about the black sweater worn by one of your classmates it goes the same.
Answer:
15.49 m/s
Explanation:
We know that the stopping distance is ,
=> s = u²/2(-a)
So that ,
=> 20m = u² / 2* 6m/s²
=> u² = 240m²/s²
=> u = √240 m²/s²
=> u = 15.49 m/s

The answer is True. The object is thrown away from the center of its original path due its inertia. Centrifugal force acts in the opposite direction as centripetal force. Centripetal force applies towards the center of the curvature in a spinning object. Centrifugal force is considered an apparent force while centripetal force is an actual force.
