23. How much time passes as Willie's car slows down from 88.0 ft/s to 0 ft/s? A. 1.315. B. 2.61 5. C. 5.64 5. D. 2.81 s. E. 8.98 5.The figure below contains 10 separate graphs, which represent the x-position coordinates of 10 different objects (named a through j), which are moving along a straight line parallel to the x axis. AX (m) i C + 10- a e g t (sec) b d f U. h - 10- 1. Object e comes to rest at exactly 2 instants of time? (Not at more than 2 instants and not at less than 2 instants) A. TRUE B. FALSE 2. Objects c, h, i and j are moving with constant velocity? A. TRUE B. FALSE3. Object f is the only object experiencing an acceleration which is directed always antiparallel to its velocity? A. TRUE B. FALSE The figure below contains 10 separate graphs, which represent the scalar x-components of the velocity of 10 different objects (named A through J), which are moving along a straight line parallel to the x axis. These are not the same objects described by the graphs above! AVx (m/s) A + 5+ C E G t (sec) F L -5+ B D H 4. Objects D, H, and I are always slowing down? A. TRUE B. FALSE5. Object B moves in the negative 3: direction and then in the positive x direction? A. TRUE B. FALSE 6. Objects D, E, I, and .l are always speeding up? A. TRUE B. FALSE 1. Objects C, F, G, and J are moving with constant velocity? A. TRUE B. FALSE 2 An experimental drone is observed moving along a straight line parallel to the x axis. The scalar a component ofthe drone's m velocity is given as a function of time by (3 I2 48 I +180) , where t is the number of seconds since 5 observations began. At t = D, the drone's x-position coordinate is equal to + 10 m. 12. At time t = 9 seconds, the drone is A. slowing down while moving in the positive x direction. B. slowing down while moving in the negative x direction. C. speeding up while moving in the positive x direction. D. speeding up while moving in the negative x direction. E. at rest. 13. At t = 8 seconds, the drone's speed is equal to A. 0 m/s. B. 6 m/s. C. 12 m/s. D. - 6 m/s. E. - 12 m/s. 14. When, if ever, is the drone slowing down while moving in the positive x direction? A. OSt 8. D. > 6. E. OK t 10 . B. 6 5 t
