Answer:
The correct solution is "33.62 m/s".
Explanation:
The given values are:
Speed
u = 9.8 m/s
Height
s = 52.8 m
As we know,
⇒ [tex]v^2 = u^2 + 2as[/tex]
On putting the estimated values, we get
⇒ [tex]=(9.8)^2+2\times 9.8\times 52.8[/tex]
⇒ [tex]=96.04+1034.88[/tex]
⇒ [tex]=\sqrt{1130.92}[/tex]
⇒ [tex]=33.62 \ m/s[/tex]
