Question

Which option best describes the average acceleration from 40 to 70 s?

Answer 1

C. The average acceleration is positive and smaller in magnitude than the initial acceleration.

What is average velocity?

Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.

a = Δv/Δt

where;

• Δv is change in velocity
• Δt is change in time

a = (250 - 248) / (70 - 40)

a = 0.067 m/s²

Thus, we can conclude that the average acceleration is positive and smaller in magnitude than the initial acceleration.
