Question

Two particles move in a uniform gravitational field with an acceleration g. At the initial moment the particles were located at one point and moved with velocities V1 = 1 m/s and V2 = 4 m/s horizontally in opposite directions. The distance between the particles at the moment when their velocity vectors become mutually perpendicular is (g=10m/s2)

  1. 4 m    
  2. 3 m    
  3. 2 m    
  4. 1    

The correct answer is: 3 m
