A projectile is launched into the air with initial velocity v_{0}*m / s from ground at an angle of relative to horizontal. The coordinates of the projectile, (x, y) relative to the launch point (that is, the launch point is the origin of the cooordinate system) has parametric equations x = v_{0} * cos theta*t; y = - g/2 * t ^ 2 + v_{0} * sin theta*t where t is the time in seconds since the projectile was launched and g is the local acceleration due to gravity Find an expression in terms of , , and g for the total distance traveled by the projectile.

7. (10 points) A projectile is launched into the air with initial velocity vo m/s from ground at an angle of 0 relative to horizontal. The coordinates of the projectile, (r, y), relative to the launch point (that is, the launch point is the origin of the cooordinate system) has parametric equations I = Vo cos et y = - 212 + vo sin et where t is the time in seconds since the projectile was launched and g is the local acceleration due to gravity. Find an expression in terms of vo, 0, and g for the total distance traveled by the projectile. You have to show answer to question 4
