The Atwood's machine is in motion starting from rest, then Vf = Vo + a(t).
<span>Final Velocity is given as 6.7 m/s and the time is 1.9 s thus 6.7= 0+ a(1.9) </span>
<span>then a = 6.7/1.9 = 3.526 m/s². </span>
<span>The Atwood's Machine also has the formula d= distance = 1/2a(t²) </span>
<span>distance given is 6.365 m , then 6.365 = 1/2 a (1.9)², </span>
<span>a = 3.526 m/s² the same acceleration. </span>
<span>a= g(m1-m2) / m1+m2) </span>
<span>m1a + m2a = m1g - m2g </span>
<span>m1a - m1g = -m2g - m2a </span>
<span>3.526 m1 - 9.81 m1 = -9.81m2 - 3.526 m2 </span>
<span>-6.28 m1 = -13.34 m2 </span>
<span>0.47 m1= m2 </span>
<span>if 24J = 1/2mv² </span>
<span>then 24J = 1/2 m1 ( 6.7)² </span>
<span>48/ 44.89 = m1 </span>
<span>1.069 kg = m1 , then </span>
<span>0.47(1.069) = m2 </span>
<span>0.503 kg = m2</span>
The slope of the illustrated graph would give us the velocity of the object whose motion is plotted in the graph.
<h3>What is velocity?</h3>
Velocity refers to the rate of movement of objects along a particular line. In other words, the velocity of an object is the speed of the object in a specific direction relative to time.
Also, velocity = displacement/time.
In the graph, the slope is given by: Δy/Δx = displacement/time = velocity.

Explanation:
A chemical reaction is a reaction in which two or more species combine together to form a molecule with a new chemical composition.
In a chemical reaction, the reactants are written on left hand side pointing a forward arrow towards the products which are written on the right hand side.
For example, chemical reaction between hydrogen and oxygen will result in the formation of water. The reaction equation will be as follows.
Explanation :
Given equation
This equation is balanced. because the number of reactants is equal to the number of products.
According to conservation of matter and energy,
The conservation of matter and energy states that matter can not create and can not destroy but conserved. we can only change one form to another form of the matter and energy.
So, we can say energy conserved and the ,mass of the system always same over time.
