Answer:
constant horizontal force developed in the coupling C = 11.25KN
the friction force developed between the tires of the truck and the road during this time is 33.75KN
Explanation:

Answer:
Part A:

Part B:

Explanation:
<u> Part A:</u>
- Potential energy of charge at the given point,

- Charge,
The potential energy at a point due to a charge is defined as
.
<em>where</em>,
V = electric potential at that point.
Therefore,

<u>Part B:</u>
Now, if the charge at that point is replaced with
, then the electric potential energy at that point is given by

"Energy and Momentum" is always conserved in an inelastic condition
Hope this helps!
The are elements on the periodic table
The point on the graph is above or below the 3rd division on the x-axis. But that's all we know, since you've told us nothing about the motion.
