Question

use the data table on the left to complete the calculations.
what is the elapsed time for trial b?
what is the average speed for trial b?

Explanation:

Elapsed Time for Trial B

Step1: Recall elapsed time formula

Elapsed time = Time (final) - Time (initial)

Step2: Substitute values for Trial B

Time (final) = 4.5 s, Time (initial) = 1.5 s
Elapsed time = \( 4.5 - 1.5 = 3.0 \) s

Average Speed for Trial B

Step1: Recall average speed formula

Average speed = \( \frac{\text{Distance traveled}}{\text{Elapsed time}} \)

Step2: Substitute values for Trial B

Distance traveled = 4.0 m, Elapsed time = 3.0 s
Average speed = \( \frac{4.0}{3.0} \approx 1.33 \) m/s (or \( \frac{4}{3} \) m/s)

Answer:

s:
Elapsed time for Trial B: \( \boldsymbol{3.0} \) s
Average speed for Trial B: \( \boldsymbol{\approx 1.33} \) (or \( \boldsymbol{\frac{4}{3}} \)) m/s
