Question: An object moves in a straight line with an acceleration of 2 m/s². If its initial velocity is 10 m/s, what will be its velocity after 5 seconds?
Options:
10 m/s
20 m/s
30 m/s
40 m/s
Correct Answer: 30 m/s
Solution:
Final velocity (v) = u + at = 10 + 2*5 = 20 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 10 m/s, what will be its velocity after 5 seconds?
Step 1: Identify the initial velocity (u). In this case, u = 10 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 = 5 seconds.
Step 4: Use the formula for final velocity: v = u + at.
Step 5: Substitute the values into the formula: v = 10 + (2 * 5).
