Question: An object moves in a straight line with an acceleration of 2 m/s². If its initial velocity is 5 m/s, what will be its velocity after 3 seconds?
Options:
5 m/s
8 m/s
11 m/s
14 m/s
Correct Answer: 11 m/s
Solution:
Final velocity (v) = u + at = 5 + (2 * 3) = 11 m/s.

Questions & Step-by-Step Solutions
An object moves in a straight line with an acceleration of 2 m/s². If its initial velocity is 5 m/s, what will be its velocity after 3 seconds?
Step 1: Identify the initial velocity (u). In this case, u = 5 m/s.
Step 2: Identify the acceleration (a). Here, a = 2 m/s².
Step 3: Identify the time (t) for which the object is moving. In this case, t = 3 seconds.
Step 4: Use the formula for final velocity: v = u + at.
Step 5: Substitute the values into the formula: v = 5 + (2 * 3).
