A projectile is fired from the origin (at y = 0 m) as shown in the diagram above. The initial velocity components are Vx = 140 m/s and Vy = 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 (Vx) of the projectile at point P?

the horizontal speed remains constant at 140 m/s
gravity only acts downward
