Projectile Motion
 

Projectile Motion problem 39


Water leaves the end of a hose pipe at point P with a horizontal velocity of .




Point P is at height above the ground. The water hits the ground at point Q. The horizontal distance from P to Q is .


Air resistance is negligible. Assume that the water between P and Q consists of non-interacting droplets of water and that the only force acting on each droplet is its weight.


  • Explain, briefly, why the horizontal component of the velocity of a droplet of water remains constant as it moves from P to Q.


  • Show that the time taken for a droplet of water to move from P to Q is .


  • Calculate height .
