Yes, because imagine a car, as it races it has a positive acceleration. So imagine the car going faster, and at the point it is at and imagine it slowing down. Compared to its previous speed is it a positive or negative acceleration (after it slowed down)?
Negative.
this is because its speed is decreasing. When anything is decreasing it is negative.
In other words its speed is decreaseing meaning its having a negative acceleration

boyakko [2]

The fatal current is 51 mA = 0.051 Ampere.

The resistance is 2,050Ω .

Voltage = (current) x (resistance)

            =  (0.051 Ampere) x (2,050 Ω)  =  104.6 volts .

==================

This is what the arithmetic says IF the information in the question
is correct.

I don't know how true this is, and I certainly don't plan to test it,
but I have read that a current as small as  15 mA  through the
heart can be fatal, not  51 mA .

If 15 mA can do it, and the sweaty electrician's resistance is
really 2,050 Ω, then the fatal voltage could be as little as  31 volts !

The voltage at the wall-outlets in your house is  120 volts in the USA !
THAT's why you don't want to stick paper clips or a screwdriver into
outlets, and why you want to cover unused outlets with plastic plugs
if there are babies crawling around.
