The graph below describes the motion of an object moving along the x-axis: For the following questions, express intervals using two letters (such as AB). The positive direction (+) points to the right. Then provide a very brief explanation why you are picking these intervals. If the vertical axis represents position, identify all intervals: (a) when the object is moving to the left.(b) when the object is slowing down. If the vertical axis represents velocity, identify all intervals: (c) when the object is moving to the right.(d) when the object is speeding up.

An object moves in the XY-plane. It starts by moving 40 cm at 50o counterclockwise relative to the positive x-axis. Then it moves 70 cm at 65o counterclockwise relative to the positive y-axis. Finally, it moves 30 cm at 35o clockwise from relative to the negative y-axis. (a) Calculate the magnitude of the resultant displacement.(b) Calculate the direction of the resultant displacement, represented as an angle measured counterclockwise from the positive x-axis.(c) If the whole journey took 7 seconds, calculate both the average speed and the average velocity of the object.

Assume 52 N We want to replace the existing force diagram with a force couple system at point B: For the following statements below, type in T for true or F for false. The resultant force at point B will the same as the applied force at B. [ans1] The resultant moment at point B will be the same as the couple moment created by the 15N forces. [ans2] If we want to replace the 15N forces with a couple moment, we would multiply 15 by: [ans3] Type in the correct letter from the choices below: a. 0.4 b. 0.24 c. 0.4 + 0.24 d. If we want to replace the force couple system at point B with a single force acting along DC, how far to the left of point C would we need to place the resultant force vector: [ans4] Type in the correct letter from the choices below: a. 0.04m b. 0.10m c. 0.14m d. 0.26m If we want to replace the force couple system at point B with a single force along AB, how far to the left of point B would we need to place the resultant force vector: [ans5] Type in the correct letter from the choices below: a. same as the answer that you found going along DC b. more than the answer you found going along DC c. less than the answer you found going along DC d. Line AB goes through point B so you cannot replace the force couple system with a single vector
