A bullet is fired horizontally aiming at an object which starts falling at the instant when the bullet is fired (as shown). Position ‘A’ is taken as origin and speed of bullet is 10 m/s. If the bullet hits the object after 1 second, then coordinates of the point where it hits the object will be [Take g = 10 m/s²]
At the time of collision both bullet and target will have same co-ordinate.
For bullet and object the displacement along y-axis is same.
∴ For Bullet: x = uₓ t = (10)(1) = 10 m
For Object: y = 1/2 ayt² = 1/2 (–10)(1)² = –5 m
∴ Coordinate = (10, –5) m
