Determine the rock's distance from the ground, in feet, after 6 seconds of free fall. (Enter an exact number as an integer, fraction, or decimal.)

Question

Suppose a rocks falls vertically off of a 1300 foot cliff. Use the distance equation for an object in free fall, d = 16t^2, to determine the rock's distance from the ground, in feet, after 6 seconds of free fall. (Enter an exact number as an integer, fraction, or decimal.)

Answer 1

d=16t^2 when t =6

d= 16(6)^2= 16(36) =576

But this distance should represent how far the brick has traveled from its original position (so you have to subtract to find your final answer)

3000-576=2424 feet
