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?
SolutionIn order to make it feasible for teachers to use these problems in their classwork, no solutions are publicly visible, so students cannot simply look up the answers. If you would like to view the solutions to these problems, you must have a Virtual Classroom subscription.
If the total momentum of the system is 0, what is the speed of the larger object?
Two cars are traveling from Oxford, Maine to Auburn, Maine, which is 18 miles away. Car B has twice the momentum of Car A. Car A takes 23.2 minutes longer to reach Auburn than Car B. If Car A had been traveling 25 mph faster, the two cars would have had equal momenta. If the mass of Car B is 1500 kg, what is the mass of Car A?
