Question

if a freely falling object were somehow equipped with a speedometer on a planet where the acceleration due to gravity is 20 m/s/s, then its speed reading would increase each second by

Answer 1

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

Step-by-step 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
