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

Elapsed time = 4.5 − 1.5 = 3.0 s

Average speed = distance / elapsed = 4.0 / 3.0 = 1.33 m/s ≈ 1.3 m/s
