Answer:
z = 93.2 m
Explanation:
We can appreciate that this expression is equivalent to the linear motion equation with constant acceleration
v² = v₀² + 2 a d
If we make a term-to-term comparison with the expression obtained, they are equivalent
u² = v² + 2 a z
From here we can clear the position
2 a z = u² –v²
z = (u² –v²) / 2 a
Let's calculate
For the speed to reduce the acceleration must be negative
z = (0 - 21.8²) / 2(- 2.55)
z = 93.2 m
Electric charge
Explanation:
The ampere-hour corresponds to the unit of electric charge.
Electric charge = electric current x time
electric current is measured in amperes
time is measured in hours
The ampere-hour is the current transferring one charge in one hour.
The ampere hour can be used to express the energy require to move a current of 1A in a hour.
The quantity is related to electric charge and the energy in a battery.
