The correct answer is:
<span>KE at 4 m/s less than KE at 6 m/s
In fact, the formula for the kinetic energy is:
</span>

<span>where m is the mass of the person and v his speed.
When the person is moving at 4 m/s, his kinetic energy is:
</span>

instead, when he's moving at 6 m/s, his kinetic energy is:

So, the kinetic energy at 4 m/s is less than the kinetic energy at 6 m/s.
Answer:
Charge, q = 1.402 C
Explanation:
Given that,
Current from lightning bolt, 
Time, t = 
Let q is the charge transferred in this event. We know that the total charge divided by time is called current. Mathematically, it is given by :



q = 1.402 C
So, 1.402 coulomb of charge is transferred in this event. Hence, this is the required solution.

The BOLD sentence above is your answer.
The S.I. unit for the measure of the pressure is the Pascal (Pa). 1 Pascal corresponds to

We can convert the number given by the problem into Pascal:

And since

, we have
