The speed of the man when he throws the coat is 1 m/s.
<h3>
Conversion of linear momentum</h3>
The speed of the man can be determined by applying the principle of conservation of linear momentum as follows;
m₁v₁ = m₂v₂
v₁ = (m₂v₂)/m₁
v₁ = (50 x 4)/200
v₁ = 1 m/s
Thus, the speed of the man when he throws the coat is 1 m/s.

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.
Answer:
There is no chemical combination of the substances in a mixture, so they retain their physical properties. There is the same composition throughout a homogeneous mixture. The structure of a heterogeneous mixture differs.
Explanation:
The definition of a Newton (unit) is an expression of a quantity as a result of a 
object acceleration.
<h3>What is the SI newton unit?</h3>
The Standard International (SI) unit of force is the newton. The letter N is frequently used to shorten the phrase "newton" in physics and engineering documents. In the absence of any other forces, one newton is the force necessary to accelerate a mass of one kilogram at a pace of one meter per second squared.
<h3>What are the equivalents of a newton in terms of mass and acceleration?</h3>
One Newton is the amount of force required to accelerate one kilogram of mass one squared meter per second.
<h3>Is the newton a measure of force?</h3>
The newton, abbreviated N, is the SI unit of force. Base units that are pertinent to force are: The symbol for the length unit of a metre is m. the kilogram (kg), a unit of mass.
