Answer:
Ví dụ 1 : Hai vật xuất phát từ A và B cách nhau 400m chuyển động cùng chiều theo hướng từ A đến B. Vật thứ nhất chuyển động đều từ A với vận tốc 36km/h. Vật thứ hai chuyển động đều từ B với vận tốc 18km/h. Sau bao lâu hai vật gặp nhau ? Gặp nhau chỗ nào
Facing disagreement forces scientists to prove their theories more conclusively.
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.
True. Because say if you go to a junk place where you can break anything and you decide to squish a printer with a car and when you go look at the printer it’s all deformed there’s really no way that you can fix it. Lol that was an example
The answer is 72.2 to 3 significant figures
