Question

stone piece is just dropped from a height of 18 M if its velocity increasing family at the rate of 10 m s -2 with what velocity will it strike the ground how much time does the stone take to reach ground

Answer 1

if you satisfied with my answer can you please mark as brainlest answer.

Answer 2

  We know that    

        s = ut + 1/2a t²

       ⇒180 = 0 + (1/2)(10)t²

       ⇒180 = 5  t²

       ⇒180/5 = t²

       ⇒36  = t²

       ⇒√36 = t

       ⇒t = 6

∴Time taken is 6 seconds
