Question: A particle moves along a straight line with an acceleration of 2 m/s². If its initial velocity is 3 m/s, what will be its velocity after 5 seconds?

Options:

13 m/s
10 m/s
8 m/s
15 m/s

Correct Answer: 13 m/s

Solution:

Using the equation v = u + at, where u = 3 m/s, a = 2 m/s², and t = 5 s, we get v = 3 + (2 * 5) = 3 + 10 = 13 m/s.

Questions & Step-by-Step Solutions

A particle moves along a straight line with an acceleration of 2 m/s². If its initial velocity is 3 m/s, what will be its velocity after 5 seconds?

Step 1: Identify the initial velocity (u). In this case, u = 3 m/s.
Step 2: Identify the acceleration (a). Here, a = 2 m/s².
Step 3: Identify the time (t). In this problem, t = 5 seconds.
Step 4: Use the formula for final velocity: v = u + at.
Step 5: Substitute the values into the formula: v = 3 + (2 * 5).
Step 6: Calculate the product of acceleration and time: 2 * 5 = 10.
Step 7: Add the initial velocity to the result from Step 6: v = 3 + 10.
Step 8: Calculate the final velocity: v = 13 m/s.
