A classical mechanics problem by Akhilesh Ganeshkar
A Particle is projected from a point ( 0 , 1) on Y-axis(assume +Y direction vertically upwards ) aiming towards a point (4,9). It fell on the ground ( i.e. X-axis ) in 1 sec. Taking g=10m/s^2 and all coordinates in metres. Find the X-coordinate of the particle where it fell.
