How far will a free falling object fall in 8.7 secs if it started from rest? remember acceleration is negative for free fall. do not use a negative number for "how far" the object fell.

h~=371.26m

Explanation:

when an object falls we use the equations of accelerated motion. There is only one that gives distance.

Since we have no initial velocity (started from rest) we can get rid of the (ut) term

where a we substitute g (gravitational acceleration, constant for given heights and almost 9.81m/s^2).
