1. a stone is dropped from the top of a tower. when it crosses a point 5 m below the top, another stone is let fall from a point 25m below the top. both stones reach the bottom of the tower simultaneously. find the height of the tower. g=10

dear jadhayla

time taken for 25 ms=(2*25/9.8)^0.5

time taken for 5 mis = (2*5/9.8)^0.5

total time taken  = (2*h/9.8)^0.5 = (2*25/9.8)^0.5 + (2*5/9.8)^0.5

total height = 52.306 m
