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 +

Put u = 0 and a=-g

2

2 x 0.32-0.32

=

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.
