A rifle bullet is fired at an angle of 30 below the horizontal with an initial velocity of 800 m/s from the top of a cliff 80 m high. How far from the base of the cliff does it strike the level ground below?
 
  What will be an ideal response?

Question 2

What does it mean to say something (for example charge) is quantized?

Answer to Question 1

138 m

Answer to Question 2

A quantized something comes in basic units and occurs as an integer number of these basic units. For example, isolated objects will be found to have a charge plus or minus ne where n is an integer and e = 1.6  10-19 Coulombs.
