1. 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   110 m   20 m   160 m   Hint Half-n-half Clue   2. The line segment BC on the distance vs. time graph given above indicates that the object is moving at a constant speed.   True   False   3. Both speed and velocity have the same units of measurement.   True   False   4. If velocity is measured in meters per second and time in seconds, then the units of acceleration are   second2 / meter   meter / second2   second / meter   meter / second   Half-n-half Clue   5. A scalar is a quantity which has both magnitude and direction.   True   False   6. A bus covers a distance of 150 miles in 3 hours. Its average speed in miles per hour is   5   50   450   None of these   Half-n-half Clue   7. If an object moves through equal distances in equal times, then it is moving at a constant _______.   velocity   speed   acceleration   displacement   Half-n-half Clue
