    How was this equation [v=4212x/(x+0.5)] derived? Did you derive the equation or the equation was given to you ? What is the domain of V(x)?

    Sure, the equation v=4212x/(x+0.5) represents a velocity equation for a projectile being accelerated, where 4212 is the theoretical max...

    OP, you have to ignore my reply. It is based on: \displaystyle \int dt = \int \frac{x + 0.5}{4212} \ dx 😭 This is the last time to...
