Answer:

25.8 meter

Explanation:

body will continue for 2 sec upward after 2sec

  1. u=0 and hight coverd is 19.2m
  2. use h=ut+1/2at²
  3. now we have 3 more sec left
  4. again use formula in point 2 and calculate total hight by putting the value t=3
  5. you will get 45 m
  6. now minus the height coverd in 1st point ... you will get the answer
