Question

A stone is dropped from a tower 100 meters above the ground. The stone falls past ground level and into a well. It hits the water at the bottom of the well 5.00 seconds after being dropped from the tower. Calculate the depth of the well. Given: g = -9.81 meters/second2.

Answer 1

hlo mate

here is your answer

given height,s=500m

                g=10

       speed of sound =340

 on analysing we get that  we have to find time period

first analyze the data and apply different formulas for it then see which formula suits the best.

         the formula that should be used here is

                                   s=ut+1/2at2

                          u=0,

                  500=0+1/2x10xtxt

we get t=10 sec

 now the time for the resound=500/340=1.47 sec

 total time=10+1.47=11.47 sec.
