At a height of h meters, you can see V kilometers to the horizon. These numbers are related by the equation V=3.5sqrt(h). A person can see 364 km to the horizon from an airplane window. How high is the airplane? The airplane is__ meters high. 2. The formula r=2sqrt5L can be used to approximate the speed r, in miles per hour, of a car that has left skid marks of length L, in feet. How far will a car skid at 50 mph? The car will skid _feet. Thank you!Answer by nerdybill(6962)   (Show Source): You can put this solution on YOUR website!1. At a height of h meters, you can see V kilometers to the horizon. These numbers are related by the equation V=3.5sqrt(h). A person can see 364 km to the horizon from an airplane window. How high is the airplane? . The problem gives you V (364) you just need to find h: The airplane is 10816 meters high. . 2. The formula r=2sqrt5L can be used to approximate the speed r, in miles per hour, of a car that has left skid marks of length L, in feet. How far will a car skid at 50 mph? The car will skid 125 feet.
