Mech Motion in two dimensions N-22 4. An object moves clockwise along the trajectory below (top view shown). The acceleration varies, but is always directed toward point K. a. On the diagram below, indicate the direction of the acceleration at each of the points A-G. Top view b. For each of the points A-G, state whether the object is speeding up, slowing down, or neither. e. On the diagram below, draw a velocity vector for each of the points A-G. The relative magnitudes of these vectors should be qualitatively correct. Top view 5. Suppose that an object were to move at constant speed around an S-shaped curve as shown at right. The S-shaped curve is made of two half circles and a straight segment. E At each of the indicated points on the diagram, draw a vector to represent the acceleration of the object. If the magnitude of the acceleration is zero at any of these points, indicate so explicitly. E Top view Acceleration vectors for constant speed
