Question

1. if i start out at 3 m/s and accelerate at 5 meters per second squared, for 18 seconds, what is my final velocity?

Explanation:

Step1: Identify the formula

The formula for final velocity \(v = u+at\), where \(u\) is the initial velocity, \(a\) is the acceleration and \(t\) is the time.

Step2: Substitute the values

Given \(u = 3\space m/s\), \(a=5\space m/s^{2}\), \(t = 18\space s\)
\(v=3 + 5\times18\)

Step3: Calculate the result

First, calculate \(5\times18=90\)
Then \(v=3 + 90\)

Answer:

\(93\space m/s\)
