Question

An object travels half its total path in the last second of its fall from rest. Find the following:
A) Total time it falls
B) The height of its fall

Answer 1

Time to fall \[t=\sqrt{2h/g}\] Height of fall: \[h=1/2(g)(t)^{2}\div2\]

Answer 2

Where g = 9.8m/s^2, t = time, and h = height.

Answer 3

Thank you!

Answer 4

Assuming the only force considered is gravity for practical purposes; By this we mean ignoring air resistance, earth magnetic field and any other existing external forces.
