falling stone accelerates at ani costant tate of 10 meter per second. It is dropped from rest down ani deep well,and 3 second later ani splash is hesed as it hita’iin the wayee below.
A, how fast it be moving as it hits the wayee?in detail
man, where did you learn to type?
If the depth of the well is h, then
5t^2 = h
If the speed of sound is s, then
t + h/s = 3
solve those for t, and then the speed at impact is 10t
