Question

when a 1.5 gram stone is dropped from 80 feet what time the stone takes​

Answer 1

Answer:

Explanation:

time cannot vary with mass ,,,,,GALILEO experiment

t =(2h/g)^1/2                      h :height =80m

                                          g: acceleration due to gravity =32m/s2

t= (2*80/32)^1/2 =5^1/2 = 2.23s
