U know the formula
V^2=u^2+2*g*h
Given u=0
h=2.9m

@perl HELP lol

@janello  shamim is right

perl · Answer

you can use the formula 
v^2=u^2+2*g*h

v = final speed (here speed of impact) 
u = initial speed (here zero)
g = acceleration due to gravity  (9.8 m/s^2)
h = height (here 2.9 meters)
