Projectile Motion The horizontal distance that a projectile will travel in the air (ignoring air resistance) is given by the equation R ( θ ) = v 0 2 sin ( 2 θ ) g where v 0 is the initial velocity of the projectile, θ is the angle of elevation, and g is acceleration due to gravity ( 9.8 meters per second squared). a. If you can throw a baseball with an initial speed of 34.8 meters per second, at what angle of elevation θ should you direct the throw so that the ball travels a distance of 107 meters before striking the ground? b. Determine the maximum distance that you can throw the ball. c. Graph R = R ( θ ) , with v 0 = 34.8 meters per second. d. Verify the results obtained in parts (a) and (b) using a graphing utility.
