1. Consider the graph of distance (in m) vs. time (in s) given above. The object's speed during the first 5 seconds is   4 m/s   5 m/s   20 m/s   100 m/s   Hint Half-n-half Clue   2. If an object moves through equal distances in equal times, then it is moving at a constant _______.   speed   acceleration   velocity   displacement   Half-n-half Clue   3. Consider the graph of velocity (in m/s) vs. time (in s) given above. In the first 8 seconds, the object has traveled a distance of   100 m   20 m   160 m   110 m   Half-n-half Clue   4. Acceleration = (change in _______) / (time taken for that change)   force   displacement   speed   velocity   Half-n-half Clue   5. The rate of change of displacement is called   velocity   force   acceleration   speed   Half-n-half Clue   6. If an object starts from rest and attains a velocity of 20 feet per second after 5 seconds, then its acceleration in feet per second2 is   4   100   500   None of these   Half-n-half Clue   7. The line segment BC on the distance vs. time graph given above indicates that the object is moving at a constant speed.   True   False
