← The kinetic energy of a moving trolley is found from K = 1/2mv². The mass has an error of 2% and the speed an error of 3%. What is the largest possible percentage error in K?To find g = (4π² L)/T², a student measures the length of a pendulum as L = (100.0 ± 0.1) cm and the time for 20 swings as (40.0 ± 0.1) s. What is the percentage error in g? →
