5) A projectile is fired from the ground with the initial velocity vo = 45 m/s, 53 above the horizontal. a. How long will the projectile be in the air? Vx = V b. What is the horizontal range? c. What is the maximum height the projectile reaches? d. What is the projectile's velocity at the highest point? 6) A cannon ball is fired from a cannon located at the edge of 34-m-tall cliff. The initial velocity of the cannon ball has a magnitude of 540 m/s and an angle 42 above the horizontal. a. How much time is required for the cannon ball to reach the ground? b. What is the speed of the cannon ball right before it hits the ground? c. What is the maximum height reached by the cannon ball from the ground
