Answer:
The answer is "151.25 J and -547.64 J".
Explanation:

Using formula:

Calculating the Work by net force
The above work is converted into thermal energy.
Now,

P2o3 is <span>diphosphorus trioxide.
Add water and you get phosphoric acid</span>
Answer: 25N
method: total force in the right hand direction is 100N and total force in the left hand direction is 125N. To get the net force, we add forces if they are in the same direction and substract if they are in opposite directions. since 100N and 125N are in opposite directions, we substract the larger value from the smaller value. Then we get 25N in the left hand direction as the final answer.
