Answer:
0.8 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.81 m/s²
In the y axis
From the equations of motion we have
[tex]v^2-u^2=2gs\\\Rightarrow v=\sqrt{2gs+u^2}\\\Rightarrow v=\sqrt{2\times 9.8\times 3.3+0^2}\\\Rightarrow v=8.04238\ m/s[/tex]
[tex]v=u+gt\\\Rightarrow t=\dfrac{v-u}{g}\\\Rightarrow t=\dfrac{8.04238-0}{9.8}\\\Rightarrow t=0.82065\ s[/tex]
It takes 0.8 seconds to strike the ground
