A rock is thrown upward from the level ground insuch a way that the maximum height of its flight is equal toits horizontal range R. (a) At what angle θ is the rock thrown?(b) In terms of the original range R, what is the range Rmax therock can attain if it is launched at the same speed but at theoptimal angle for maximum range? (c) Would your answer topart (a) be different if the rock is thrown with the same speedon a different planet? Explain.
