A dart is thrown at a dartboard 3.90 m away. When the dart is released at the same height as the center of the dartboard, it hits the center in 0.555

To find the speed at which the dart was thrown, we need to use the formula for horizontal distance:
d = v * t
where d is the distance, v is the velocity, and t is the time.
In this case, the horizontal distance, d, is given as 3.90 m, and the time, t, is given as 0.555 seconds.
Plugging in the values:
3.90 = v * 0.555
To isolate v, we divide both sides of the equation by 0.555:
v = 3.90 / 0.555
v ≈ 7.03 m/s
Therefore, the dart was thrown at a speed of approximately 7.03 m/s.
