Solve the problem.The path of a projectile fired at an inclination ? (in degrees) to the horizontal with an initial speed v0 is a parabola. The range R of the projectile, that is, the horizontal distance that the projectile travels, is found by using the formula R = 
sin(2?)where g is the acceleration due to gravity. The maximum height H of the projectile is H = 
(1 - cos(2?))Find the range R and the maximum height H in terms of g if the projectile is fired with an initial speed of 200 meters per second at an angle of 15° and then at an angle of 22.5°. Do not use a
calculator, but simplify the answers. What will be an ideal response?
