The figure shows a position-time graph for the motion of an object. Which of the following are true of the motion from 0 s to 10 s? Select all correct answers. Position vs. Time Position (metres) 50 0 -50 -100 0 2 4 6 8 10 Time (seconds) The average velocity vector is positive. The average velocity vector is negative. The instantaneous speed is increasing. The instantaneous speed is decreasing. The average acceleration is positive. The average acceleration is negative.

Step 1
The average velocity vector is positive: To find the average velocity, we need to find the total displacement divided by the total time. The displacement is the final position minus the initial position. In this case, the final position is 50 and the initial Show more…

The figure describes the position of an object as a function of time. Which one of the following statements is true at t = 1 s? The x-component of the velocity of the object is zero. The x-component of the velocity of the object is negative. The x-component of the acceleration of the object is zero. The x-component of the velocity of the object is positive.

The figure shows the graph of the position s of an object as a function of time t. For each interval [0, 10], [10, 20], and so on, indicate whether the acceleration is negative, zero, or positive. (Please enter your answer as negative, zero, or positive.) [0, 10] is [10, 20] is [20, 30] is [30, 40] is [40, 50] is
