Answer:

F = K Q1 Q2 / R^2         force between 2 charges separated by R

F2 / F1 = (R1 / R2^2)    dividing equations

F2 / F1 = (R1 / 3 R1)^2 = 1/3^2 = 1/9

The force would be reduced by a factor of 9

3.8 / 9 N = .42 N

Answer:

s = 90 m

a = 56 m/s²

Explanation:

I will ASSUME that your equation is silly as it reduces to V = 11t which is constant, and that you mean V = 9t² + 2t

Position is the integral of differential velocities

s = \int\limits^3_0 {9t^2 + 2t} \, dt

s = 3t³ + t² | from 0 to 3

s = 3(3)³ + 3² - (0) = 90 m

acceleration is the derivative of velocity

a = v' = 18t + 2

a(3) = 18(3) + 2 = 56 m/s²
