Question

A student is working in a lab to determine how time affects impulse. The student keeps the force the same in each trial but changes the impact time. Some data is shown.

A 3 column table with 4 rows. The first column is labeled Trial with entries, Trials 1, Trial 2, Trial 3, Trial 4. The second column is labeled Force in Newtons with entries 500N, 500N, 500N, 500N. The third column is labeled time in second with entries 0.25, 0.15, 0.45, 0.33.
Which trial has the greatest impulse?

trial 1
trial 2
trial 3
trial 4

Answer 1

Impulse = force × time. With F = 500 N:

- Trial 1: 500×0.25 = 125 N·s
- Trial 2: 500×0.15 = 75 N·s
- Trial 3: 500×0.45 = 225 N·s
- Trial 4: 500×0.33 = 165 N·s

Greatest impulse: trial 3.
