Astudent is testing the kinematic equations for uniformly accelerated motion by measuring the time it takes for light-weight plastic balls to fall to the floor from a height of 3 m in the lab. the student predicts the time to fall using g as 9.80 m/s2 but finds the measured time to be 35% greater. which of the following is the most likely cause of the large percent error?
(a) the acceleration due to gravity is 70% greater than 9.80 m/s2 at this location.(b) the acceleration due to gravity is 70% less than 9.80 m/s2 at this location.(c) air resistance increases the downward acceleration.(d) the acceleration of the plastic balls is not uniform.(e) the plastic balls are not truly spherical.
