Question

Which of the following quantities cannot be calculated by directly using the third equation of motion?

  1. Initial velocity
  2. Acceleration
  3. Displacement
  4. Time

hintHint:

The third equation of motion gives the final velocity of an object under uniform acceleration given the distance and initial velocity.

The correct answer is: Time


    Time cannot be calculated by directly using the third equation of motion.
    The third equation of motion is v squared space minus space u squared space equals space 2 a s
    Where, v= final velocity
    u = final velocity
    a = acceleration
    s = displacement.
