1. The problem statement, all variables and given/known data

Hi! Ive to try and solve "use two opamp integrators to solve the differental acceleration of an object falling under the force of gravity d^2y/dt^2 = 10"


2. Relevant equations

Vout = -1/Rc * integral (Vin dt)


3. The attempt at a solution

I'm really stuck as to how to approach this! Ive gotten as far as the voltage being potential difference and the work can be given by force * distance and RC is the time constant for a capacitor but i dont know where to go next if anyone could offer some help itd be great!
thanks
