Select two pieces of information that are necessary to calculate an object's average speed A. square magnitude of the objects acceleration B. total time the object was in motion C. square direction of the objects motion D density of the object. total mass of the object E total distance the object traveled

To calculate an object's average speed, we need to know the total distance the object traveled and the total time the object was in motion. <br /><br />The formula for average speed is:<br /><br />\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \]<br /><br />So, the two pieces of information necessary are:<br /><br />B. Total time the object was in motion<br />E. Total distance the object traveled
