If a ball is dropped near the surface of the earth, then the distance it falls is directly proportional to the square of the time it has fallen. A ball is dropped over the edge of a vertical cliff and falls 39.2 meters in two seconds.
Determine the distance (in meters) the ball would have dropped in 3.5 seconds.
The ball would have dropped ____ meters. Round your answer to two decimal places

Best ResponseYou've already chosen the best response.1\[x \propto t^2 \implies x = k t^2\] \[\therefore k = \dfrac{x_1}{t_1^2} = \dfrac{x_2}{t_2^2}= \dfrac{x_3}{t_3^2} = \ldots\]

Best ResponseYou've already chosen the best response.1? the distance it falls is directly proportional to **the square of** the time it has fallen more time, bigger drop, and its squared too.....
