Aball in flight is recorded and analyzed using digital video analysis software. the analysis produced the result that the ball had a horizontal speed of 0.30 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. a) was the horizontal speed actually faster or slower than the analysis result? b) what should the result have been for the horizontal speed?
