C. 29 m/s
Basing on the information given, we can compute for the velocity with the following
Mass = 11 lb. convert to kg = 5 kg
Gravity = 9.8 m/s2
Time (final) = 3.0 s
v= at
v = 9.8m/s2(3.0s)
= 29.4 m/s

Explanation:
Acceleration is the change in speed over time.
The object accelerates from 0 meters per second to 25 meters per second in 5 seconds.
Substitute the values into the formula.
Solve the numerator.
Divide
The object's acceleration is 5 meters per square second.
