A 6-column table with 3 rows in the second, third, and fifth columns and 1 row in the other columns. The first column labeled Number of Washers has entry 1 washer mass = 4.9 grams. The second column labeled Trial has entries trial number 1, trial number 2, trial number 3. The third and fourth columns labeled Time to travel 0.25 meters t subscript 1 (seconds) have entries in the third column 2.24, 2.21, 2.23 and average 2.23 in the fourth column. The fifth and sixth columns labeled time to travel 0.5 meters t subscript 2 (seconds) have entries in the fifth column 3.16, 3.08, 3.15 and in the sixth column average 3.13.
What is the average velocity of the car over the first 0.25m?
m/s
What is the average velocity of the car over the second 0.25m?
m/s
To find the average velocity, we divide the total displacement by the total time.
For the first 0.25m:
Total displacement = 0.25m
Total time = Average time from the third column = 2.23s
Average velocity = Total displacement / Total time
= 0.25m / 2.23s
For the second 0.25m:
Total displacement = 0.25m
Total time = Average time from the fifth column = 3.13s
Average velocity = Total displacement / Total time
= 0.25m / 3.13s
The average velocity of the car over the first 0.25m is approximately 0.1123 m/s.
The average velocity of the car over the second 0.25m is approximately 0.0799 m/s.
