Answer:
38.218 m
Explanation:
Horizontal projectile motion is there.(graph)
applying motion equations for downward motion
(only a horizontal velocity is there. stone is subjected to the gravity )
Sv = height
u = initial velocity
t= time taken
[tex]S_v=ut+\frac{1}{2}*at^{2} \\19.4=0+\frac{1}{2}*10*t^{2} \\t=1.97 s[/tex]
for horizontal motion
Sh= horizontall distance
[tex]S_h=ut\\s=19.4*1.97\\s=38.218 m[/tex]
