When you throw a pebble straight up with initial speed V, it reaches a maximum height H with no air resistance. At what speed should you throw it up vertically so it will go twice as high? 16 V 8 V 4V 2V squareroot 2V

Explanation:

Velocity at maximum height is 0 m/s. With initial velocity, V, height h and acceleration of gravity, g,

g is negative because the motion is against gravity.

If the maximum height were doubled, then we have
