A projectile is fried from the origin (at y=0 m) as shown in the diagram. The initial velocity components are Vox=310 m/s and Voy=26 m/s. The projectile reaches maximum height at point p, then it falls and strikes the ground at point q, which is 20 m below the launch point. For how long is the projectile in the air? 3.4 s
6.0 s
6.8 s
4.5 s
9.3 s
