Dropping the phone answer

In my previous blog post I had a question to find the final velocity of my phone before it hit the floor. Assume the locker shelf is 1.8m high. Now we will be able to find the final velocity using the formula vf^2=vi^2+2ad. vf^2=0^2+2(9.81m/s/s)(1.8m). vf^2=2(9.81m/s/s)(1.8m). vf^2=35.316m^2/s^2. Square root vf^2= Square root 35.316m^2/s^2 vf=5.9m/s. My phone hit the floor with a velocity of 5.9 m/s.
