Problem
Two particles are simultaneously thrown horizontally from two points on a riverbank at the same height above the water surface. Their initial velocities are v1=5 m s−1 and v2=7.5 m s−1, respectively. Both particles fall into the water at the same time. The first particle enters the water at a point s=10 m from the bank. Determine:
(1) The time of flight of the two particles.
(2) The height from which they are thrown.
(3) The point where the second particle falls in water.
