Question

A projectile is fired from the origin (at y = 0 m) as shown in the diagram. The initial velocity components are140 m/s and 84 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. Assuming air resistance is negligible, what is the horizontal component of the velocity ( V x) of the projectile at point P?
