Answer:
Object, starting from rest, will fall at 137.34m/s after 14s.
Step-by-step 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
