Question

On a distant planet a freely falling object has an acceleration of 25 m/s2 . Calculate the vertical distance an object dropped from rest on this planet covers in 1.5 s .

Answer 1

delta_y = vi*t + 1/2at^2

Answer 2

plug and play.

Answer 3

What is delta_y?

Answer 4

the change in the height

Answer 5

\[\lim_{t \rightarrow 1.5}\frac{ dx }{ dt }\]

where x = 1/2at^2

first find the derivative and then plug in t = 1.5
and remember a = 25 m/s^2 since we're on a distant planet and not Earth

Answer 6

I got 28 m

Answer 7

yep.

Answer 8

That's wrong.
