Kinematics

A water fountain on the ground sprinkles water all around it. If the speed of water coming out of the fountain is v, the total area around the fountain that gets wet is

  1. πv4/2g2
  2. πv2/g2
  3. πv4/g2
  4. πv2/g

Answer

Rmax = (v2/g) sin2θ = v2/g

Area = πR2 = πv4/g2

The correct option is C.
