Question

If an object is dropped from rest and falls 16m before hitting the floor, how long does it fall for?
(Take acceleration due to gravity to be 10m s-2)

Answer 1

Answer:

The formula for free fall is x=1/2gt^2 so basically 10=(9.81/2)t^2 t=1.43 s. ... t (s) = SQR [2 • 10 (m) / 9.8 (m/s^2)]. t (s) = SQR[20 (m) ... A ball is dropped from a height of 25 meters from rest.
