Answer: The speed reading would increase each second by 20m/s

Explanation:

Acceleration is the change in velocity per unit change in time.

Acceleration = velocity/time

∆v = a∆t

Given a = g = 20m/s/s (acceleration due to gravity)

∆t = 1 sec

∆v = 20m/s/s * 1s

∆v = 20m/s

Therefore, the speed reading would increase each second by 20m/s
