As above, so bellow, G-2.2m/s2 = 30N is the newtons, then divide by G.
Problem, you probably pull fish sideways not up, becaus it's easier.
Again, we need to know kinetic force of the truck which is derived from weight, mass, whatever, the ability to remain in constant motion.
We account acceleration only in getting straight down, multiplied by the minus of friction, ... I don't understand if you accelerate pointing to a ground causing bigger friction on a flat ground or down hill.
We calculate the total trajectory of parallel line of a triangle where she is pushed down... straight with ground. calculate the velocity she will reach in mv^2 with energy, aling for friction, therefore multiply by 1 - friction... We have her gain of energy per second, then we have result.
Sorry for my latex, but I don't want to scare kids with numbers.
