• 1.

  A ball is projected vertically up with speed \( V_0 \) from a certain height \( H \). When the ball reaches the ground, the speed is \( 3V_0 \). The time taken by the ball to reach the ground and height \( H \) respectively are:

  • \( \frac{V_0}{g} \), \( \frac{V_0^2}{2g} \)
    
  • \( \frac{V_0}{g} \), \( \frac{3V_0^2}{2g} \)
    
  • \( \frac{2V_0}{g} \), \( \frac{V_0^2}{2g} \)
    
  • \( \frac{3V_0}{g} \), \( \frac{3V_0^2}{2g} \)
