# Velociraptor and Mosasaurus

Pro Problems > Physics > Momentum## Velociraptor and Mosasaurus

A 33 pound velociraptor, in an attempt to catch a pterodactyl, leaps horizontally off a cliff. At the moment he starts to fall, a mosasaurus weighing 15 tons begins launching vertically out of the water from a depth of 20 meters, accelerating constantly during the 4 seconds he is in the water. The velociraptor and the mosasaurus collide in mid-air. If the two dinosaurs have equal and opposite momenta at the moment of the collision, how tall is the cliff, to the nearest meter?
