Answer:

Object, starting from rest, will fall at 137.34m/s after 14s.

Explanation:

Assuming that the object falls from rest (ie it's dropped, not thrown), initial velocity, u, is equal to 0m/s.

Assuming this object is falling on earth, the acceleration it undergoes due to gravity, a, is equal to 9.81m/s².

We are looking for v, the final speed at t=14s.

v=u+at

=0+(9.81)(14)

=137.34m/s
