When fighting a fire the velocity V of water being pumped into the air is modeled by the function v=√2hg, where h represents the maximum height of the water and g represents the acceleration due to gravity (32 ft/s^2)
The Jackson Fire dept must purchase a pump that will propel water 90ft into the air. will a pump advertised to project water with a velocity o f 77 ft/sec meet the dept need? explain
