How far does it travel in the time between t = 3.0 s and t = 4.0 s? A 28 m B 35 m C 48 m D 64 m 5 In a experiment, a student jumps upward off a common bathroom scale as the laboratory partner records the scale reading. What does the laboratory partner observe during the instant the student pushes off? A The scale reading will remain unchanged during the entire time the student is in contact with the scale. B The scale reading will increase momentarily then will decrease during the entire time the student is in contact with the scale. C The scale reading will decrease then increase during the entire time the student is in contact with the scale. D The scale reading will decrease during the entire time the student is in contact with the scale. 6 A 1000 kg mass was placed 2 m directly above a 1 kg mass and bot
