Question

11 formula 1.5 points what is the acceleration of a vehicle if its initial speed was 9 m/s, and its final acceleration was calculated at 48 m/s, and this change happened in a period of 7 seconds? note: only type in the numerical value. round up your answer to only 1 decimal if needed answer

Explanation:

Step1: Recall the formula for acceleration

The formula for acceleration \(a=\frac{v - u}{t}\), where \(v\) is the final velocity, \(u\) is the initial velocity, and \(t\) is the time.

Step2: Substitute the given values

Here, \(u = 9\space m/s\), \(v=48\space m/s\), and \(t = 7\space s\).
So, \(a=\frac{48 - 9}{7}=\frac{39}{7}\)

Step3: Calculate the value

\(\frac{39}{7}\approx5.6\)

Answer:

\(5.6\)
