Question

I drop a quarter from a 2 story house. It takes 1.85 to hit the ground. what was the velocity

Answer 1

At the instant you dropped it from your hand, its speed was zero.
The coin gained 9.8 m/s every second it fell. At the end of 1.85 sec,
just before it went 'tink' onto the ground, its speed was

(9.8 m/s) x (1.85 sec) = 18.13 m/s .

Its velocity at that final instant was 18.13 m/s downward.
