Question

A 3-column table with 5 rows. The first column has entries empty, distance travelled (meters), time (initial) (seconds), time (final) (seconds), elapsed time (seconds), average speed (meters per second). The second column labeled Trial A has entries 4. 0, 2. 0, 2. 5, 1. 5, 2. 7. The second column labeled Trial B has entries 4. 0, 1. 5, 4. 5, empty, empty. Use the data table on the left to complete the calculations. What is the elapsed time for Trial B? s What is the average speed for Trial B? m/s.

Answer 1

Speed is the ratio of distance and time

• The elapsed time is 3 seconds
• The average speed is 1.33 meters per second

How to calculate the elapsed time

The elapsed time is the difference between the final time and the initial time.

So, we have:

Time elapsed = 4.5 seconds - 1.5 seconds

Evaluate the difference

Time elapsed = 3 seconds

Hence, the elapsed time is 3 s

How to calculate the average speed

The average speed is the quotient of the distance and the elapsed time.

So, we have:

Average speed = 4 meters/ 3 seconds

Evaluate the quotient

Average speed = 1.33 meters per second

Hence, the average speed is 1.33 m/s
