5. Two objects were dropped from the same height with an interval of one second. If there is no air Resistance, what can you say about the difference in their speed? A) increases C) remains constant B) decreases D) cannot be determined 6. An object is moving forward with constant non-zero acceleration. The velocity versus time graph of this object is A) a curve. B) a vertical straight line. 7. If the velocity versus time graph of an object is a horizontal line, the object is A) at rest C) moving with zero acceleration B) moving with increasing speed. D) moving with constant non-zero acceleration. 8. You accidentally drop a pen from the third floor of SM San Lazaro straight down to the ground. If we take upward as the positive direction, which of the graphs shown below best represents the acceleration of the pen as a function of time starting at time = 0? K 2.0 C) a horizontal straight line. D) a straight line making an angle with the time axis. 9. The motions of a car and a truck along a straight road are represented by the velocity-time graphs in the figure. The two vehicles are initially alongside each other at time t = 0. Truck G Car -2.0 B) At time T, what is true of the distances traveled by the vehicles since time t = 0? A) They will have traveled the same distance. B) The truck will not have moved. 9 1.0 2.0 3.0 4.0 time UUD 10. The graph in the figure shows the position of an object as it travels along the distance (x). distance (x) C) The truck will have travelled further than the car. D) The car will have travelled further than the truck. -4.0 At what value of time is the speed of the object equal to 0 m/s?
