Questions 1 3 relate to two objects that start at x 0 at t 0 and move in one dimension independently of one another Graphs of the velocity of each object versus time are shown below Object A 2 v m mc 1 04 4 of 1 0 2 01 10 i Which object is farthest from the origin at t 2 seconds A A B B C they are in the same location at t 2 seconds D They are the same distance from the origin but in opposite directions 3 Which object is in its initial position A A B B C both A and B t sec Which object moves with constant non zero acceleration A A B B C both A and B D neither A nor B Velocity m s Object B v m ec 10 A 1 0 2 0 101 at t 2 seconds D neither A nor B 14 0 t sec Time s The graph above shows the velocity versus time for an object moving in a straight line At what time after t 0 does the object again pass through its initial position A 1 s B Between 1 and 2 s C 2 s D Be veen 2 and 3 s 5 A body moving in the positive x direction passes the origin at time t 0 Between t 0 and t 1 second the body has a constant speed of 24 meters per second At t 1 second the body is given a constant acceleration of 6 meters per second squared in the negative x direction The position x of the body at t 11 seconds is A 99m B 36m C 36 m E 99 m 6 A diver initially moving horizontally with speed v dives off the edge of a vertical cliff and lands in the water a distance d from the base of the cliff How far from the base of the cliff would the diver have landed if the diver initially had been moving horizontally with speed 2v A d B 2d C 2d D 4d
