Question

the distance that a body falls through when dropped from a certain height varies directly with the square of the time of fall. A body falls through a total of 500m in 10 seconds. find the distance it falls through, in 9th second (in m)

Please help me solve this

Answer 1

Let g = 10 m/s^2.

d = 0.5g*t^2 = 5*9^2 = 405 m.
