Question

The velocity of a bus increases by 20 m/s in 80 seconds. What is the

acceleration of the bus?
A. 0.25 m/s2
B. 4 m/s2
C. 60 m/s2
D. 100 m/s2

Answer 1

A

Step-by-step explanation:

velocity is measured in m/s

acceleration has units m/s^2

so divide the velocity change by the time change:

20 m/s / 80 s = 20 / 80 = .25 m/s^2
