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 sin 24, where r is the range (in feet), vo is the initial speed (in ft/s), @ is the angle of elevation the bali 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 8 (0< 8< 45°) is doubled. b. If a ball travels a horizontai distance of 20 ft when kicked at an angle of a with initial speed of 20/2 tus, find the horizontal distance it can travel when you double a. Hint: use result of item (a).
