Answer:
30 m/s
Explanation:
Velocity is [tex]v_{final}=v_{initial}+at[/tex] since we know that the initial velocity is 0, and the acceleration is [tex]9.8 \frac{m}{s^2} \approx 10 \frac{m}{s^2}[/tex] then we also know that time is 3 seconds it follows that: [tex]v_{final}=v_{initial}+at=0+10\frac{m}{s^2}*3s=30\frac{m}{s}[/tex]
