How Far does the sled move in the time interval t = 0 to t = 1 . 6 s ? Answer in units oF m. 007 10.0 points A student throws a baseball at a large gong 67 m away and hears the sound oF the gong 1 . 57038 s later. The speed oF sound in air is 330 m / s. What was the average speed oF the base-ball on its way to the gong? (±or simplicity, assume its trajectory to be a straight line.) Answer in units oF m / s. 008 10.0 points A man jogs at a speed oF 1 . 4 m / s. His dog waits 1 . 3 s and then takes o² running at a speed oF 3 m / s to catch the man. How Far will they have each traveled when the dog catches up with the man? Answer in units oF m....
