Answer
Explanation:
It is given that,
The horizontal speed of a dart player =
12.4 m/s
The dart hits the board 0.32 m below the
height from which it was thrown.
We need to find how long it take the dart
to hit the board.
Let the time taken by the dart to hit the
board. Using second equation of motion
to find it.

y = ut +
2
=
at2
Put u = 0 and a=g

y =
1942

0.32
=
x 9.8t2
2
2 x 0.320.32
=
t=
9.8
t= 0.255 s
Let x be the horizontal distance travelled.
It is calculated as follows:
X =
12.4 x 0.255
=
= 3.16 m
So, the dart will hit the board at a
distance of 3.16 m.
