A freely falling body,starting from rest,falls 16 ft during the first second,48 ft during the second,second,80 ft during the third second,etc.
Calculate the distance it falls during the fifteenth second and the total distance it falls in 15 seconds from rest.
:
Find the total dist of the 14th sec subtracted from the 15th second
f(t) = 16(15^2) - 16(14^2)
f(t) = 3600 - 3136
f(t) = 464 ft during the 15th second
A total of 3600 ft
