Answer:
The value is [tex]v = 24.5 \ m/s [/tex]
Explanation:
Generally from kinematic equation we have that
[tex]v = u + at[/tex]
Here u is equal to zero given that the batch was at rest
a is equal to the g which has a value [tex]g = 9.8\ m/s^2[/tex]
and t is 2.5 \ s
So
[tex]v = 0 + 9.8 * 2.5 [/tex]
[tex]v = 24.5 \ m/s [/tex]
