Hint: Find the time it will take an object to freely fall 10 cm under the influence of gravity, then use distance = speed times time to find the horizontal distance.
Hi I just need to see how to approach a problem like this.
A darts player throws a dart at a dart board which hangs vertically. The motion of the dart is modelled as that of a particle moving freely under gravity. The darts move in a vertical plane which is perpendicular to the plane of the dart board. A dart is thrown horizontally with speed 12.6 m s^-1. It hits the board at a point which is 10cm below the level from which it was thrown.
Find the horizontal distance from the point where the dart was thrown to the dart board.
Thanks!
