Answer:
4.8%
Explanation:
percentage error can be calculated as the difference between the theoretical and experimental value divided by the experimental value expressed in percentage.
The percentage error can be computed mathematically as
(accepted value - experimental value)/accepted value × 100
accepted value = 63 m/s
experimental value = 66 m/s
difference = 63 - 66 = -3 m/s
use the absolute value = 3 m/s
percentage error = (accepted value - experimental value)/accepted value × 100
percentage error = 3/63 × 100
percentage error = 300/63
percentage error = 4.76%
percentage error = 4.8%
