Math Problem Statement
Question content area top Part 1 A projectile fired from the point (0,0) at an angle to the positive x-axis has a trajectory given by y equals Cx minus left parenthesis 1 plus Upper C squared right parenthesis left parenthesis StartFraction g Over 2 EndFraction right parenthesis left parenthesis StartFraction x Over v EndFraction right parenthesis squared . In this formula, x is the horizontal distance in meters, y is the height in meters, v is the initial velocity in meters per second, gequals9.81 m divided by sec squared is the acceleration due to gravity, and Upper C greater than 0 is a constant determined by the angle of elevation. A howitzer fires an artillery round with a velocity of 883 m/sec. Answer parts (a) and (b). Question content area bottom Part 1 (a) If the round must clear a hill 156 meters high at a distance of 1946 meters in front of the howitzer, what C values are permitted in the trajectory equation?
