Answer:

Vf = 14 [m/s]

Explanation:

To solve this problem we must use the following equation of kinematics, which is independent of the mass of the object.

[tex]v_{f} ^{2} =v_{o} ^{2} +(2*g*x)[/tex]

where:

Vf = final velocity [m/s]

Vo = initial velocity = 0

g = gravity acceleration = 9.81 [m/s²]

x = distance = 10 [m]

Now replacing:

Vf² = 0 + (2*9.81*10)

Vf = 14 [m/s]
