    A body is thrown upward against the gravity ‘g’ with initial velocity ‘u’. Which one among the following is the correct expression for its final velocity when the body attains the maximum height?

  • u2/(2g)
  • 2g/u2
  • u2g/2
  • None of the above
  • Explanation:

    The final velocity for a body thrown upwards is always 0. However, the maximum height attained by the body can be given by the expression u2/2g derived from the formula v2 - u2 = 2gs, where u is the initial velocity, v is the final velocity and s is the height attained
