Answer :

Explanation : h =v²/2g
h =9m²/s²/20m/s²
h = 0.45 m

  • Initial velocity=u=3.0m/s
  • Acceleration due to gravity=g=9.8m/s^2

Neglate air resistance.

  • So acceleration is unchanged
  • As acceleration is remaining constant so at the top the velocity is 0.
  • But at the end the velocity again come to 3m/s.
