25 20 15 10 b.) Suppose that some object is constrained to move on a straight line as depicted in the sketch below. (+) [m/s] 0 t [s] -5 5 78 9 10 -10 -15 -21 -25 And suppose that the motion of the object is described by the shown velocity vs time graph, where the positive and negative values of the velocity refer to the direction of motion. a) What is the average acceleration of the object from t = 0 seconds to t = 3 seconds. b) What is the average acceleration of the object from t = 5 seconds to t = 7 seconds. c) What is the object's displacement in the first 5 seconds of its motion? 25 20 15 10 b.)
