While standing on a bridge 19.0 m above the ground, you drop a stone from rest. When the stone has fallen 3.50 m, you throw a second stone straight down. What initial velocity must you give the second stone if they are both to reach the ground at the same instant? Take the downward direction to be the negative direction.

You cast a pebble at 1.8 m/s at a pond from 0.7 m above ground. How fast is it when it is about to land in the pond 0.9 m below the ground? Hint: use mechanical energy conservation. The direction of the velocity is irrelevant. It doesn't have to travel straight up or down. Pebble's final position is negative.
