A zookeeper with a tranqualizer dart gun and a monkey (1.5kg) are both 25 m above the ground in trees 90 m apart. Just as the zookeeper shoots the gun, the monkey drops from the tree. What must the minimum muzzle velocity of the dart have been for it to hit the monkey before reaching the ground?

Im not sure how to start this...so the monkey would be falling at 1/2 gt^2. And at sometime the dart and the monkey will be at the same Y. How would i set up the equations to solve this? Thanks
