Vy = 28 - 9.8t
So, how lonmg is it in the air? Find t such that
26t - 4.9t^2 = -20
Help would be much appreciated!
A projectile is fired 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. When the projectile reaches point Q, what is the vertical component of its velocity?
