A ball in flight is recorded and analyzed using digital video analysis software. The analysis produced the result that the ball had a horizontal speed of 0.60 m/s. In the analysis, a stick was used as a calibration standard, and it was believed that the stick was 1.0 m long. However, after the analysis was done, it was discovered that the stick was actually 0.90 m long.
Was the horizontal speed actually faster or slower than the analysis result?
What should the result have been for the horizontal speed (Vx)?
