1. A car moves at an average speed of 30 miles per hour. In 2 hours, it will travel a distance of   3 miles   15 miles   60 miles   None of these   Hint Half-n-half Clue   2. 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   110 m   160 m   20 m   100 m   Half-n-half Clue   3. A scalar is a quantity which has both magnitude and direction.   True   False   4. A toy plane moves at a constant speed of 3 m/s. It will travel a distance of 42 m in   14 s   126 s   140 s   None of these   Half-n-half Clue   5. If an object moves through equal distances in equal times, then it is moving at a constant _______.   displacement   velocity   speed   acceleration   Half-n-half Clue   6. Consider the graph of velocity (in m/s) vs. time (in s) given above. During the last 2 seconds, the object   reduces its velocity from 10 m/s to zero.   is constantly decelerating at 10 m/s2.   covers a distance of 10 m.   is constantly accelerating at 10 m/s2.   Half-n-half Clue   7. Acceleration can be negative.   True   False
