Make sure you are using the correct values and that your calculations are correct. It's always a good idea to double check your work to ensure accuracy. 3. Make sure you are using the correct formula. In this problem, you are looking for the height of the tower, so you should be ...
In summary, the speed of a particle at a height h can be found by first determining the initial kinetic energy at height zero, and then using the fact that the change in kinetic energy is equal to the change in potential energy. This results in the formula √v2 - 2gh for the speed ...
