Given:
u(intial velocity)=0
a(acceleration)=9.8 m/s^2(as it is a free falling object acceleration is due to gravity)
t= 3 seconds
In order to find the final velocity v
We know that
v= u+at
Where v is the final velocity measured in m/s
u is the initial velocity measured in m/s
a is the acceleration measured in m/s^2.
t is the time taken to fall down measured in seconds
Now substituting the given values in the above formula we get
v=u +at
v=0+(9.8 x 3)
v=29.4m/s
Thus the final velocity is 29.4 m/s.
