Answer:

$F_f=840N$

Explanation:

From the question we are told that

Weight of fireman $W_f= 87.5kg$

Pole distance $D=4.10m$

Final speed is $V_f 1.75m/s$

Generally the equation for velocity is mathematically represented as

$v^2 = v_0^2 + 2 a d$

Therefore Acceleration a

$a'= v^2 / 2 d$

$a'= 0.21m/s^2$

Generally the equation for Frictional force $F_f$ is mathematically given as

$F_f=m*a$

$F_f=m*(g-0.21)$

$F_f=87.5*(9.81-0.21)$

Therefore

$F_f=840N$

Explanation:

A battery is an electrochemical cell that converts chemical energy into electrical energy. The chemical reactions in a battery ensures that current is produced.

A battery is made up of two electrodes which are the cathode and anode.
The cathode is the positive electrode and the anode is the negative one.
These electrodes are made up of metals.
Electrons moves from the anode to the cathode and current flows from cathode to anode.
At the anode oxidation occurs because electrons are produced here.
It needs to have low electron affinity.
At the cathode where reduction occurs, the electron affinity must be high.
This is the driving force for the production of electricity in electrochemical cells.
