(01.04 LC)Consider the common measurement: acceleration = 2.3 m/s2 down. Which of the following is considered the direction in this measurement?

(01.09 LC)A graph is presented below, representing an object’s motion.Which of the following times is the object at rest?

(01.08 HC)During an experiment, the time of an object was measured every 20 meters. Each researcher measured the object’s motion on different surfaces, noted as A, B, C, and D. Their average data of the trials are shown below. Distance (cm) 0 20 40 60 80 100 Time A (s) 0 5.23 10.11 14.68 18.54 22.36 Time B (s) 0 4.66 9.33 13.97 18.63 23.31 Time C (s) 0 3.57 7.44 11.32 16.98 23.28 Time D (s) 0 5.00 15.00 40.00 60.00 85.00 Which of the surfaces allowed the object to increase its speed the entire distance of travel?
