A projectile is launched from and returns to ground level, as the figure shows. There is no air resistance. The horizontal range of the projectile is measured to be R = 175 m, and the horizontal component of the launch velocity is υ_0x = +25 m/s. Concepts:

(i) What is the final value of the horizontal component υ_x of the projectile’s velocity?

(ii) Can the time be determined for the horizontal part of the motion?

(iii) Is the time for the horizontal part of the motion the same as that for the vertical part?

(iv) For the vertical part of the motion, what is the displacement of the projectile? Calculations: Find the vertical component υ_0y of the projectile.
