Solution
Solution Steps
Step 1: Identify the Given Values
We are given the following values:
Initial velocity, \( v_i = 8.46 \, \text{m/s} \)
Final velocity, \( v_f = 9544 \, \text{m/s} \)
Time taken, \( t = 1.94 \, \text{s} \)
Step 2: Use the Formula for Acceleration
The formula for acceleration \( a \) is given by:
\[
a = \frac{v_f - v_i}{t}
\]
Step 3: Substitute the Given Values into the Formula
Substitute the given values into the formula:
\[
a = \frac{9544 \, \text{m/s} - 8.46 \, \text{m/s}}{1.94 \, \text{s}}
\]
Step 4: Perform the Calculation
Calculate the numerator:
\[
9544 - 8.46 = 9535.54
\]
Now, divide by the time:
\[
a = \frac{9535.54}{1.94} \approx 4915.25 \, \text{m/s}^2
\]
