Question: If a body is moving with a uniform acceleration of 2 m/s², what will be its velocity after 5 seconds if it starts from rest? (2023)

Options:

Correct Answer: 10 m/s

Exam Year: 2023

Solution:

Using the formula v = u + at, where u = 0, a = 2 m/s², t = 5 s. v = 0 + (2 × 5) = 10 m/s.

If a body is moving with a uniform acceleration of 2 m/s², what will be its velocity after 5 seconds if it starts from rest? (2023)

If a body is moving with a uniform acceleration of 2 m/s², what will be its velocity after 5 seconds if it starts from rest? (2023)

Step 1: Identify the initial velocity (u). Since the body starts from rest, u = 0 m/s.
Step 2: Identify the acceleration (a). The problem states that the acceleration is 2 m/s².
Step 3: Identify the time (t). The problem states that the time is 5 seconds.
Step 4: Use the formula for final velocity (v): v = u + at.
Step 5: Substitute the values into the formula: v = 0 + (2 m/s² × 5 s).
Step 6: Calculate the result: v = 0 + 10 m/s = 10 m/s.
Step 7: Conclude that the velocity after 5 seconds is 10 m/s.

Uniform Acceleration – Understanding how velocity changes over time when an object accelerates at a constant rate.
Kinematic Equations – Application of the kinematic equation v = u + at to solve for final velocity given initial conditions.
Initial Conditions – Recognizing that the initial velocity (u) is zero when the body starts from rest.
