The acceleration is 
Explanation:
We can solve the problem by applying Newton's second law of motion: in fact, the net force acting on an object is equal to the product between the mass of the object and its acceleration. Therefore we can write:
where:
is the resultant force acting on the object
m is its mass
a is its acceleration
In this problem, we have the following forces acting on the system:
(forward)
(backward)
So, Newton's second law can be rewritten as:
where:
m = 1050 kg is the mass of all the students
Solving the formula for a, we find the acceleration of the system:

answer is that i think???
An Energy Transfer Diagram is also known as Sankey diagram and this shows the input energy taken in and the transformation of the output energy in another form. Therefore the basis for analyzing an energy transfer diagram would be the sum of all outputs must equal the input. Therefore, it is the third option. Hope this answer helps.
The energy transformations that occur as you coast down long hill on a bicycle, including the brakes to make the bike stop at the bottom, is that at the top of the hill you have high GPE AND LOW KE, on your way down you have HIGH KE AND LOW GPE, and at the bottom you have thermal energy due to the stop of the brakes.
the law of conversation of energy and describe the energy transformations that occur as you coast down a long hill on a bicycle and then apply the brakes to make the bike stop at the bottom.
