Chapter , Problem 54(choose chapter or problem)
A ball is to be shot from level ground with a certain speed. Figure 4-45 shows the range R it will have versus the launch angle \(\theta_{0}\). The value of \(\theta_{0}\) determines the flight time; let \(t_{\max }\) represent the maximum flight time. What is the least speed the ball will have during its flight if \(\theta_{0}\) is chosen such that the flight time is 0.500\(t_{\max }\)?
