5. A ball is thrown following a projectile motion. It is known that the horizontal distance (range) the ball can travel is given by R Do %3D sin 20, wherer is the range (in feet), vo is the initial speed (in ft/s), 0 is the angle of elevation the bail is thrown, and g=32 ft/s? is the acceleration due to gravity. a. Express the new range in terms of the original range when an angle e (0< 0 < 45°) is doubled. b. If a ball travels a horizontal distance of 20 ft when kicked at an angle of a with initial speed of 20V2 ft/s, find the horizontal distance it can travel when you double a. Hint: use result of item (a).
