As per your syllabus, what is the AVERAGE velocity of the same object between t = 2.0 s and t = 4.0 s?
A6 m/s
B15 m/s (using Δx/Δt with x = a + bt²)
C10 m/s
D12 m/s
Answer & Solution
Correct answer: B. 15 m/s (using Δx/Δt with x = a + bt²)
As per your syllabus, avg vel = [x(4)−x(2)]/(4−2) = (16b−4b)/2 = 6b = 6 × 2.5 = 15 m/s.
