What is the car's speed after it has traveled 200. meters? 1960 m/s 62.6 m/s 44.3 m/s 31.3 m/sAfter a model rocket reached its maximum height, it then took 5.0 seconds to return to the launch site. What is the approximate maximum height reached by the rocket? [Neglect air resistance] 49 m 1 98 m O 120 m 250 mf a C e b Select which of the above vectors have the same direction Oa&b Ob &e Oa&e Oc& fWhich graph below represents the motion of an object at rest? O O 0The graph represents the relationship between distance and time for an object that is moving along a straight line. What is the instantaneous speed of the object at t = 5.0 seconds? Distance (m) Time (s) 0.0 m/s 0.8 m/s 2.5 m/s 4.0 m/s 6.8 m/sWhich of the following is true? If velocity is zero, then acceleration must be zero too. Acceleration and velocity are always in the same direction. Two objects side by side must have the same speed. None of the aboveAn athlete runs at 6 m/s north for a distance of 12 000 m, then turns around and walks at 2 m/s south back to her original position. How long does it take her to walk back to her original location? 2 000 s 4 000 s 6 000 s 24 000 sWhich of the following is a vector quantity?

Onone of the above are trueAn object with an initial speed of 4.0 meters per second accelerates uniformly at 2.0 meters per second2 in the direction of its motion for a distance of 5.0 meters. What is the final speed of the object? C 6.0 m/s 10. m/s 14 m/s 36 m/sWhich of the following situations describes zero acceleration? a rock falling from a cliff a cannonball being shot into the air a wagon rolling at a constant velocity of 4 m/s a toy car coming to a stop as it rolls onto a rocky pathA sky diver jumps out of a hovering helicopter. A few seconds later, another sky diver jumps out, and they both fall along the same vertical line. Ignore air resistance, so that both sky divers fall with the same acceleration. Doe the difference in their speeds stay the same throughout the fall? Does the vertical distance between them stay the same throughout the fall? Explain your solution in full sentences and support your answer with sample calculations (use the insert equation option to show formulas and math steps).
