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

Respuesta :

Answer:

A

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
