Assuming no friction form air, how far will a dropped rock fall in 10 seconds
serious [3.7K]

<u>Given that</u>

time (t) = 10 s ,

         (S) = ?

We know that  S = ut+ 1/2 a.t²  m

                         since free fall and no air friction,

                               a = g = 9.81 m/s² ; initial velocity u= 0

                         S = 0 + [1/2 × 9.81 ×10²]

                       <em>   S = 490.5 m </em>
