m2 core review of motion

T. William is trapped on a number line where each number represents a meter. He begins at 0 m mark, walks to -6 m position and then back to +3 m position. What distance did he cover?

• 3 m

• -6 m

• 9 m

• 15 m

Same situation: T. William is trapped on a number line where each number represents a meter. He begins at 0 m mark, walks to -6 m position and then back to +3 m position. What is the magnitude and direction of his displacement?

• • + 3 m

• • - 6 m

• + 9 m

• • + 15 m

In this situation, T. William is trapped on the same number line where each number represents a meter. This time he begins at the +3 m mark, walks to -6 m position and then to 0 m position. What is the magnitude and direction of his displacement?

• • + 3 m

• • - 3 m

• + 9 m

• • + 15 m

Same situation: T. William is trapped on the same number line where each number represents a meter. He begins at the +3 m mark, walks to -6 m position and then to 0 m position. If the total change in position took 30 seconds, what was the average speed of his motion?

• • + 0.1 m/s

• • - 0.1 m/s

• 0.5 m/s

• 2 m/s

Same situation: T. William is trapped on the same number line where each number represents a meter. He begins at the +3 m mark, walks to -6 m position and then back to 0 m position. If the total change in position took 30 seconds, what was his velocity?

• • + 0.1 m/s

• • - 0.1 m/s

• 0.5 m/s

• 2 m/s

Same situation: T. William is trapped on the number line where each number represents a meter. He begins at the +3 m mark, walks to -6 m position and then back to 0 m position. The total change in position took 30 seconds to complete. Which of the following graphs depicts his displacement?
