A cylindrical column of water that is 1 cm in diameter falls from a fountain and hits the ground vertically with a speed of 30 cm/s. When it hits the ground, it splashes horizontally in all directions. Estimate the force that the water exerts on the ground. Water has a density of 1 gram per cubic centimeter. Hint: during a short time interval dt, how much momentum is transfered between the water and the ground?
