Uniform Linear Motion of a car and SUV csBE8E838 Distance (meters) 1 2 3 4 5 B Time (seconds) Q Which statement correctly describes the motion of the two car system? Both cars are accelerating because the slope of a distance versus time graph represents acceleration. Both cars are traveling towards the right because right is always defined as the positive direction. The red car travels at a speed of about 5 m/s faster than the blue car. The slope of a distance versus time graph represents speed and the difference in the slopes is about 5. The red car travels at a speed about 1.5 times faster than the blue car. The slope of a distance versus time graph represents speed and the blue car has a slope of 1 m/s and the red car has a slope of 1.5 m/s.

In a velocity versus time graph, the object's position equals the area between the graph and the horizontal axis. In a velocity versus time graph, the object's displacement equals the area between the graph and the horizontal axis. Uniform acceleration means that an object's velocity is constant. Uniform acceleration means that an object's velocity changes at a constant rate. O e Which two of these graphs represent an object moving with non-zero acceleration? Select two answers. Question 3 1 pts During a test, a rocket is launched straight up into the air with an initial speed of 60 m/s. The speed initially increases with a constant upward acceleration of 2.5 mf:;2 until the engines stop. When the engines stop, the rocket is at a height of 300 meters. Which statement is correct? I. We can determine the amount of time the engines were used. II. At the moment when the engines have been on for half of their total run time, the rocket will be at a height of greater than 150 meters.

The object moved in the positive direction with constant acceleration from time t = 0 seconds to time t = 50 seconds. The object began moving in the positive direction speeding up, then continued moving in the positive direction with a constant velocity, and finally began moving in the positive direction slowing down. The object began moving in the positive direction slowing down, then continued moving in the positive direction with a constant velocity, and finally began moving in the positive direction speeding up.

As shown above in the top figure, the first runner initially has the baton running with a constant speed towards the second runner who is initially at rest. After a few seconds, the second runner begins to accelerate from rest to the right while the first runner continues running at a constant speed. As soon as the first runner catches up to the second runner, the first runner hands off the baton to the second runner and the first runner begins to slow down while the second runner continues running in that direction and accelerates to their maximum running speed. Finally, the first runner comes to a stop and turns around walking to the left while the second runner continues running at their maximum running speed to the right. Which of the following sets of graphs shows a reasonable representation of the velocities of the two runners as a function of time?
