Question

distance covered by free falling body in 2 seconds is

Answer 1

Answer:

   s = 19.6m

Explanation:

intial velocity (u) = 0 because the body is free falling i.e. dropped from rest

intial velocity (u) = 0   ,    time (t) = 2s    ,     acceleration (g) = 9.8m/s²

s = ut + gt² / 2

s = 0 + 9.8 × 2 × 2 / 2

s = 9.8 × 2

s = 19.6m 0r 20m (if g=10m/s²)
