0 ft/sec

He just dropped the hammer, so it's initial velocity is zero ft/sec.

Answer:

I am sorry if this wrong. I believe the initial velocity is 20.

Step-by-step explanation:

My reasoning is because the -16t^2 is representing the time. The h for height we are trying find the height. So that leave us with the initial velocity 20.

I apologize if this wrong. Hope this helps!

Have a great day/night!
