Solve the problem.The path of a projectile fired at an inclination ? (in degrees) to the horizontal with an initial velocity 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 where g is the acceleration due to gravity. Suppose the projectile is fired with an initial velocity of 400 feet per seconds and
per second2. What angle ?,
would you select for the
range to be 2500 feet? (There should be two values of ?.) Fill in the blank(s) with the appropriate word(s).
