<h2>
Answer:
joules</h2>
Explanation:
From the first law of thermodynamics,
Δ
=Δ
+
Where
is the heat given to the gas,
is the internal energy of the gas,
is the workdone by the gas.
When pressure is constant,


When pressure is constant,
Δ
Where
is pressure and
is the volume of the gas.
Given 
Δ

So,
Given that Δ
So,Δ

Using the kinematic equation below we can determine the distance traveled if t=2, a=7.4m/s^2. First we must determine the final velocity:

Now we will determine the distance traveled:

Therefore, the drag racer traveled 81.83 meters in 2 seconds.

In order for a hypothesis to be tested, and experiment needs to be designed.
Many trials need to be runned in order to get accurate results and to form a valid conclusion that can prove or disprove the hypothesis
