If it takes a ball dropped from rest 2.000 s to fall to the ground, from what height h was it released?

In a free-fall motion, the distance covered by the object in free fall is given by:

where g is the gravitational acceleration and t is the time taken to cover a distance S. In this case, the distance S is the height h from which the ball has been dropped: to find its value, we can substitute t=2.0 s into the formula, and we get

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
