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

0.25m/s2

Explanation:

Acceleration is simply the change in velocity per unit time. It is expressed mathematically as:

Acceleration (a) = change in velocity (ΔV) / time (t)

a = ΔV/t

Data obtained from the question include:

Change in velocity (ΔV) = 20 m/s

Time (t) = 80 secs

Acceleration (a) =.?

Applying the equation a = ΔV/t, the acceleration of the bus can be obtained as follow:

a = ΔV/t

a = 20/80

a = 0.25m/s2

Therefore, the acceleration of the bus is 0.25m/s2

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