Answer:
The correct answer will be "16.74 m/s".
Explanation:
The given values are:
Speed = 1.90 m/s
Height = 5.10 m
g = 9.8 m/s²
On applying energy conservation, we get
⇒ [tex]\frac{1}{2}mV_{1}^2+mgH=\frac{1}{2}mV_{2}^2[/tex]
On putting the estimated values, we get
⇒ [tex]V_{2}=\sqrt{1.9^2+2\times 9.8\times 5.1}[/tex]
⇒ [tex]=\sqrt{3.61+2\times 9.8\times 5.1}[/tex]
⇒ [tex]=\sqrt{5.61\times 9.8\times 5.1}[/tex]
⇒ [tex]=\sqrt{280.38}[/tex]
⇒ [tex]=16.74 \ m/s[/tex]
