A projectile shot over level ground hits the ground with a velocity of 65m/s at an angle of 25° below the horizontal. What was the horizontal range of the projectile? 170m 330m 780m 360m If something is launched over a horizontal plane, does Vi=Vf? (same magnitude and velocity) (but different direction obviously). Would I then be able to find Vix and Δt to find the Δx (range)?
