Answer: 22.54 m/s and 25.921 meters
Explanation:
hey dog have you ever heard of these cool equations..
[tex]v=v_{o} + at[/tex]
dude what DOES THIS MEAN??? ok ill tell you. velocity equals initial velocity plus acceleration times time. uhh... interesting.... hmm...
lets do some substitution...
we know that a means acceleration and gravity is a type of acceleration. ok?
[tex]v = 0 + (9.8)(2.3)[/tex]
remember I PUT THE ZERO THERE BECAUSE IT STARTED AT REST
22.54 is the velocity
now for b. look at THIS COOL NEW EQUATION
[tex]delta Y = \frac{1}{2}at^{2} + v_{o}t[/tex]
ok so i put delta Y but it can also be delta X it just means displacement... i put delta Y because these kids are falling straight down in a rollercoaster like space mountain or something... ok lets do some replacing am i right?...
[tex]\frac{1}{2}(9.8)(2.3^{2}) + 0(2.3)[/tex]
LISTEN! forget about the zero times 2.3 its just gonna be zero anyways.
so lets calculate... and we get 25.921 meters (or if you want to round to 2 sig figs then its 26 meters)
have a swag day
