To determine the maximum height for the projectile, we can use the timeless kinematics equation 
and plug in what we know. For 
, we know it is zero because at the highest location of flight, there is no vertical velocity. For 
, we know it is 
since the vertical component is the sine of the velocity. We need to solve for 
, so it is left as-is. Since the only acceleration is 
, we can substitute -9.81 into it. Solving for the equation yields a solution of 17.55 m for 
.

Explanation:
Take at look to the picture I attached you, using Kirchhoff's current law we get:
This is a separable first order differential equation, let's solve it step by step:
Express the equation this way:
integrate both sides, the left side will be integrated from an initial voltage v to a final voltage V, and the right side from an initial time 0 to a final time t:
Evaluating the integrals:
natural logarithm to both sides in order to isolate V:
Where the term RC is called time constant and is given by:
