A dart player throws a dart horizontally at a velocity of 12.7 m/s. The
dart hits the board 0.39 m below the height from which it was thrown.
How far away is the player from the board? Provide evidence.


Answer :

Answer:

Explanation:

The time needed to drop from vertical rest is

t = √(2(0.39)/9.8) = 0.282 s

d = vt = 12.7(0.282) = 3.5829... = 3.6 m
