DETAILS If a projectile is fired with an initial velocity of Vo meters per second at an angle a above the horizontal and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equations x = (vo cos(a))t y = (vosin(@))t - _ gt2 where g is the acceleration due to gravity (9.8 m/s2). (Round your answers to the nearest whole number.) (a) If a gun is fired with a = 30 and vo = 900 m/s. When will the bullet hit the ground? How far from the gun will it hit the ground? m What is the maximum height reached by the bullet? m (b) Find the equation of the parabolic path by eliminating the parameter
