The distance travelled by a falling object varies directly as the square of the time it spends in falling. If a body falls 64 feet in 2 seconds, find the distance that it will fall in 3 seconds.
A.40 feet
B.144 feet
C.1600 feet
D.4000 feet
basta yan yung sagot.dahil kung ang 2 sec ay 64 feet na agad so tumaas pa ng kaunti ang huhulugan ng object.nagsimula sa 64 ft. 2s.papuntang 144ft in 3sec.
