Answer:

2.5m/s²

Explanation:

Given the following:

Initial velocity u = 0m/s

Final velocity v = 20m/s

Time t = 4s

Required

average acceleration over this time in time interval​

Using the equation of motion

v = u + at

10 = 0 + a(4)

10 = 4a

a = 10/4

a = 2.5m/s²

Hence its average acceleration over this time in time interval​ is 2.5m/s²
