Question: A body moves in a straight line with a uniform acceleration of 2 m/s². If its initial velocity is 5 m/s, what will be its velocity after 10 seconds?

Options:

  1. 25 m/s
  2. 20 m/s
  3. 15 m/s
  4. 10 m/s

Correct Answer: 25 m/s

Solution: 

Final velocity = initial velocity + acceleration * time = 5 + 2 * 10 = 25 m/s.

Questions & Step-by-Step Solutions

A body moves in a straight line with a uniform acceleration of 2 m/s². If its initial velocity is 5 m/s, what will be its velocity after 10 seconds?
Correct Answer: 25 m/s
  • Step 1: Identify the initial velocity of the body, which is given as 5 m/s.
  • Step 2: Identify the acceleration of the body, which is given as 2 m/s².
  • Step 3: Identify the time duration for which the body is moving, which is given as 10 seconds.
  • Step 4: Use the formula for final velocity: Final velocity = Initial velocity + (Acceleration * Time).
  • Step 5: Substitute the values into the formula: Final velocity = 5 m/s + (2 m/s² * 10 s).
  • Step 6: Calculate the acceleration part: 2 m/s² * 10 s = 20 m/s.
  • Step 7: Add the initial velocity to the calculated acceleration: 5 m/s + 20 m/s = 25 m/s.
  • Step 8: Conclude that the final velocity after 10 seconds is 25 m/s.
  • Uniform Acceleration – The motion of an object where the acceleration remains constant over time.
  • Kinematic Equation – The formula used to calculate the final velocity of an object under uniform acceleration: final velocity = initial velocity + (acceleration * time).
