Consider an object moving in one dimension. We choose a coordinate system in which the +x direction points to the right and the -x direction points to the left. A. For an object that moves along the x-axis with constant acceleration, sketch a velocity versus time graph for the following four situations: 1) An object moving in the positive direction with increasing speed. -X 2) An object moving in the negative direction with increasing speed. V +x 3) An object moving in the positive direction with decreasing speed. V B. For each of the graphs above, indicate whether the acceleration points in the positive x-direction or in the negative x-direction. 1) 4) An object moving in the negative direction with decreasing speed. 2) C. For which scenario is the speed of the object increasing and it has a negative acceleration? Consider an object moving in one dimension.
