Questions & Step-by-Step Solutions

An object moves in a straight line with a velocity of 10 m/s. If it accelerates at 2 m/s² for 5 seconds, what will be its final velocity?
  • Step 1: Identify the initial velocity (u) of the object, which is given as 10 m/s.
  • Step 2: Identify the acceleration (a) of the object, which is given as 2 m/s².
  • Step 3: Identify the time (t) for which the object accelerates, which is given as 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).
  • Step 6: Calculate the acceleration part: 2 * 5 = 10.
  • Step 7: Add the initial velocity to the calculated acceleration: 10 + 10 = 20.
  • Step 8: The final velocity of the object is 20 m/s.

  • Final Velocity Calculation – Using the formula v = u + at to determine the final velocity of an object given its initial velocity, acceleration, and time.
