Uncategorized: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Uncategorized. Understanding the underlying formula is key to arriving at the correct answer below:

Using Newton's second law, acceleration \(a = F/m = 6text{ N} / 1text{ kg} = 6text{ m/s}^2\). Since the body starts from rest (\(u=0\)) and attains a final velocity \(v=30text{ m/s}\), we use \(v = u + at\). So, \(30 = 0 + 6t\), which gives \(t = 30/6 = 5text{ s}\).
