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   20 m   160 m   100 m   110 m   Hint Half-n-half Clue   2. A scalar is a quantity which has both magnitude and direction.   True   False   3. The line segment BC on the velocity vs. time graph given above indicates that the object is constantly accelerating.   True   False   4. 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   5. Both speed and velocity have the same units of measurement.   True   False   6. 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   7. If velocity is measured in meters per second and time in seconds, then the units of acceleration are   meter / second2   second2 / meter   second / meter   meter / second   Half-n-half Clue
