Answer:
The percent error of student is -5 %.
Explanation:
Given data:
measured value = 9.31 m/s²
actual value = 9.8 m/s²
percent error = ?
Formula:
% error = (measured value - actual value / actual value ) × 100
% error = (9.31 m/s² - 9.8 m/s² / 9.8 m/s²) × 100
% error = (-0.49 m/s² / 9.8 m/s²) × 100
% error = -0.05 × 100
% error = -5
