If a freely falling rock were equipped with a speedometer, by how much would its speed readings increase with each second IF it were on a planet where g = 20 m/s2?

Question

Show all work leading to your answer.

g=20 m/s^2 
              20 m/s
              V=gt 
             S=g( T ^2) / 2

Is this right ?

Henry · Answer

V = g*t V = 20*1 = 20 m/s. V = 20*2 = 40 m/s. V = 20*3 = 60 m/s. Increase = 20 m/s with each second.
