## anonymous 5 years ago 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

1. anonymous

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

2. anonymous

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

Thank you!

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.
