An object is thrown vertically from a height of #2 m# at #5m/s#. How long will it take for the object to hit the ground?

1 Answer

Answer:

It will take 1.32 seconds for the object to hit the ground.

Explanation:

If a body is projected or thrown vertically up from a height 'h' with a velocity 'u' then time taken by the body to reach the ground is
#t = [u+sqrt(u^2 + 2gh)]//g#
Consider 'g' acceleration due to gravity as #9.8m/s^2#
By substituting the values in above equation we get
#=> t= [5+sqrt((5)^2 + 2xx9.8xx2)]//9.8#
#:.t=1.32 seconds#
