Solution:
From Galileo's ratio of odd numbers distances travelled in consecutive seconds are in the order of 1:3:5:7
As distance in last second is is 7x. total distance = x+3x+5x+7x= 16x = 16×5= 80 m
An object is dropped from the top of a tower. It travels a distance 'x' in the first second of its motion and a distance '7x' in the last second. Height of the tower is :
