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.
  • Kinematics – The study of motion, specifically how velocity changes over time due to acceleration.
  • Equations of Motion – Using the equation v = u + at to calculate final velocity based on initial velocity, acceleration, and time.
