.1.038. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER 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 = (Vocos(a))t y = (vosin(a))t - 1 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 = 400 m/s. When will the bullet hit the ground? How far from the gun will it hit the ground? E What is the maximum height reached by the bullet? E (b) Find the equation of the parabolic path by eliminating the parameter. Need Help? Read It Watch It
