Question

a body dropped from a height falls 16 feet during the first second, 48 feet the second second, 80 feet the third second, and so on. Find how far the body falls during the 7th second and how far it falls during the first 7 seconds

Answer 1

d = 16 t^2
at t = 6, d = 16*36 = 576
at t = 7, d = 16*49 = 784
784 - 576 = 208
