An experimental robot travels along a straight line parallel to the x axis. During a test run, kis observed that the scalar x component of the robot's acceleration is given as a function of time by (-6+ +18)" for times in the interval OS 15 10 where t is the number of seconds since observations began. At t=0, the scalare component of the robot's velocity is equal to - 15 m/s) and the robot is located atxim 11. The robot is moving in the positive x direction during the time interval Als si 558 B. Iscisss D. OSI<3s E l<r<5s CIS153s 12. During the time interval from t - 0 tot 2 seconds, the scalar x component of the robot's average acceleration is equal to Bol/ c6 D-12 24 m A. 12 13. True or False At t= 1 second, the robot is located atx=-7m? A True B. False
A 1.40 m deep crater was created in a snow bank by a bundle of emergency food supplies which was dropped from a rising helicopter. Suppose that while creating the crater in the snow, the bundle slowed down at an approximately steaty rate of 149x109 m. coming to rest after descending 1.40m into the snow. 14. Which of the following diagrams correctly describes the bundle's motion while it was creating the crater? A) B) *V=0 ду (1.40 my ду ду (1.40 my (1:40 •Vr-0 •Vr-0 D) E) ду ду (1.10 m •V1-0 (1.0m •Vr-0 15. How fast was the bundle traveling just before its impact with the surface of the snowbank? A 14.45 8274 C 204 m, D. 524 £ 980 5
