The velocity at the maximum height will always be 0. Therefore, you will count your final velocity as 0, and your initial velocity as 35 m/s. Next, we know that the acceleration will be 9.8 m/s^2. How? Because the ball is thrown directly upward, and the only force acting on it will be the force of gravity pushing it back down.
The formula we use is h = (Vf^2 - Vi^2) / (2*-9.8m/s^2)
Plugging everything in, we have h = (0-1225)/(19.6) = 62.5 meters is the maximum height.
CO₃
Explanation:
The polyatomic ion in the compound CaCO₃ is CO₃.
A polyatomic ion is an ion that is made up of more than one atom that has singular property.
They are usually called radicals.
CaCO₃ ⇒ Ca²⁺ + CO₃²⁻
CO₃²⁻ is a polyatomic ion because it is made up of more than one atom.
The CO₃²⁻ is called a carbonate group.
It is made up of:
- one atom of carbon
- 3 atoms of oxygen
- a net charge of 2-
