The distance, expressed in inches, is(1.2) x (the particle's average speed, in feet per minute) .
it's answer "c"
Ignoring air resistance, or bouncing off the sides of the shaft on the way down ...-- Speed when you let it go = 0-- Speed after 6 seconds = 6 G = 58.84 meters per second-- Average speed = 1/2 (0 + 58.84) = 29.42 meters per second-- In 6 seconds, at an average speed of 29.42 meters per second,it fell 176.5 meters.
