A student is testing the UAM equations by measuring the time it takes for light-weight plastic balls to fall to the floor from a height of 5 m in the lab. The student predicts the time to fall using g as 9.80 m/s^2 but finds the measured time to be 42.5% greater. Which of the following is the most likely cause of the large percent error? a. The acceleration due to gravity is 57.5% greater than 9.80 m/s^2 at this location. b. The acceleration due to gravity is 57.5% less than 9.80 m/s^2 at this location.
