What is the average speed, over the first 1.0 s of its motion, of a pebble released from rest off a bridge?
Answers: 2
of the pebble is 
 where 
is the G-force's acceleration.![\ \textless \ v\ \textgreater \ =\int_0^1v(t)dt=\left[\frac12gt^2\right]_0^1=\frac g2](/tpl/images/0497/9655/2a65d.png)
we therefore have an average speed of
