If a freely falling object were equipped with a speedometer on a planet where the acceleration due to gravity is 20 m/s², then its speed reading would increase each second by If a freely falling object were equipped with a speedometer on a planet where the acceleration due to gravity is 20 m/s², then its speed reading would increase each second by .a. 10 m/s. b. 30 m/s. c. 20 m/s. d. 40 m/s. e. depends on its initial speed

20 m/s

Explanation:

The acceleration of an object determines the increase in velocity per second.

In this case the acceleration is 20m/s^2.

That is, the increase is 20m/s each second.

I hope this is useful for you

velocity will increase 20 m/sec each second

Explanation:

Given that the acceleration due gravity is

We have to find the increase in the speed each second

We know that acceleration is nothing but rate of change of velocity as it changes   so the speed will also changes with 20 m/sec  

the object is falling freely so initial velocity u =0 m/sec

Acceleration due to gravity g= 20 m/s²

Time = 1 sec

From first law of motion

the velocity will increase 20 m/sec each second

the answer is a)
